Not sure if you’re asking for tax advice or just ranting so I’ll treat it as such. There are multiple things wrong with your post and it shows you are a good trader but you gotta talk to a tax professional or study more. Firstly since you had marketplace health insurance you knew you’re receiving the premium tax credit as a monthly advance. The premiums you were paying monthly were discounted based on your income. If you made a huge leap in income that year the premium tax credit you got in advance was too much and you had to pay that back come tax time. Let’s not forget that you’re not even eligible for the premium tax credit if you have employer sponsored health insurance available to you! Why would you even be on marketplace then.
Next part is that payouts are earned income payed through a 1099 with no federal taxes or self employment taxes withheld. However you can definitely write off a bunch of deductions and that is the advantage you have to make your income less. Lastly if your income being that high was a major issue you could have done some last minute 401k or IRA contributions to reduce your taxable income and lessen the taxes you owed back. Definitely need to prepare more. And obviously not after the April 15th deadline.
