Desperate for help calculating the cost / basis using the simplest method .

Someone PLEASE help me out. I started mining BTC in late 2020 and 2021. I'm trying to file taxes, file bankruptcy and start my life over (whatever is left of it ) but the amount of proceeds is drastically changing my refund amount and I'm sure I didn't profit that much.

I'm a rookie miner, l'm sure I made several rookie mistakes, but I don't want to pay for it forever by reporting incorrectly to the IRS.

I downloaded a crypto calculator, Input the measly 34 transactions only to have to pay $50-$499 for the results, not only can I not afford it- I only need it for 2021 taxes. Could someone please share the simplest formula - please explain it like a fifth grader because i suck at math . Or if I could send my transactions to someone to put into a calculator I could donate a few bucks .

This is exhausting, I’m sure I’m finished trading.

Forever grateful in advance !
