I'm trying to report my cryptocurrency sales. I bought BTC on a single day, but sold on two different days and I'm having trouble with the cost basis.

I bought Cryptocurrency through CashApp, where I only bought BTC once but sold it twice - which means I only sold a partial amount of BTC and then cashed the rest out on a different day a few months later. The Cost basis under "Income" is more than what I actually paid for my BTC and I don't know how to fix it. Please help!

Thank you!
