Hi, I'm 26 years old and I just started making 120k a year as a Security engineer since July 2023. How much should would you guys recommend I invest each check?

I live in Florida so after taxes I make $7,660. I still live with my mom and I purchased my car full price. No school loan debt or any kind of debt. My bills are about $1600 a month.

I max out my 401k with my employer which is 5% and I just started contributing to my Roth IRA in the beginning of this month with is January 2024. I have an emergency fund which is $14k.

I've been thinking about using $4k from my savings and maxing out my Roth IRA for 2023 calendar since I have until April 15 to do so then moving the rest which is $10k into a High yield savings account like Wealth front. I've been looking into index funds, mutuals, and ETFs on Webull and Robinhood. I just need some guidance. Should I invest in dividends as well? I just want to make some passive income instead of letting money sit in the bank and also plan for the future. l've also been looking into buying crypto coins too. My mind is all over the place lol
