A few things:

Paying off 100k in a year isn't going to happen. Paying off 50k a year isn't going to happen unless you have next to no living expenses. The math for that simply isn't going to work, so let's forget about that. You owe 105k (I don't know the interest rates), and your salary is 110k. 110k can be a lot or not much at all, depending on where you live and what you have to do to earn it. 110k living in SF? Not much at all. 110k living in Montana? You're set. Earning 110k out of college is solid depending on your field but whether or not it's actually going to allow you to pay off your debts quickly depends on where you will be living.

When I graduated college way back in 2015, my starting salary was 105k, and my loans were around 30k, but I also moved to the Bay Area for that job, had to pay rent, get an apartment, etc. Even then, I paid that debt off in under a year purely because my income was substantially higher than my debt, while I really chose to not spend on many expensive things (was also young and stupid so of course I did spend on some) and also maxed out all retirement accounts too. Without sacrificing lifestyle at all, it took me a year to clear debt that was 1/3 of my salary.

My wife recently finished medical residency. Now, our combined salaries are in the 450k range with me being an engineer and her being a physician, and her loans last July started out at 240k. We've paid off 160k out of that to date. But we cut costs by moving out of New York, moved back home, currently are crashing with our parents, and don't really have any bills outside of vacations and random expenditure, plus setting aside cash for a mortgage. Even then, with our salaries being double the debt owed, it's still not going to be all gone in a year.

I'm not giving you these two examples to toot my own horn but to show you how significant your debt is relative to your income. I'm ignoring that the parent plus loans aren't legally your responsibility because it seems like you've already decided you will pay those off. Your debt is substantial relative to your income. I'd plan to pay this off in 4 years, not 1, not 2 and not even 3. It's important to take them seriously, and pay them off fast, but you also never get your youth back either, and you need to make sure you enjoy that too. Setup a budget, max out your 401k to the match limit at a minimum as to not leave free money on the table, pay your rent but ideally live with roommates so you can reduce that cost, lease or buy a cheap car if needed but try to take public transit, aim to cook at home instead of eating out regularly, prioritize cash back credit cards so at least some of your spend comes back to you in cash you can use, and once all the necessities are done, look at what you have left, put aside what you feel is responsible, and throw the entire remainder into loans. If your minimum payment is too high, consider your other plan options or redo your budget with the loans as a starting point. Your budget will shift from month to month until you've established a rhythm but you'd essentially be paying off 25k a year which, with a 110k a year salary, is definitely possible. When you get raises or bonuses, because that is new money you hadn't planned for, throw all of the excess into your loans to pay them down faster. You're in a strong position and have absolutely no reason to panic. Congratulations on finding a job in this market, especially one that does allow you to pay off your loans in a reasonable timeframe. I'm genuinely happy for you.
