If I may ask a follow up question:
I received some crypto units for free when I signed up to a Crypto platform (Coinbase), as part of their sign up promotion. I had sold this amount. In the transaction csv that Coinbase provided, I see the "sell" transaction. I report the amount I received as basis, and the sold price as proceed in my 8949 and schedule D. This part is fine.
Where should I put the "free" units that I originally received from Coinbase? I see the transaction, that has amount I received as cost basis, then transaction type is "reward".
