Scorpion, I am happy about your answer here. I asked someone about this at Cryptotrader.tax and they seem to think I had to send all of my 1099-B papers. When I downloaded my Form 8949 from their site they actually put 'see attached statement' in the a column for my Short Term Gains, along with the Gain and Loss totals. So I can erase the 'see attached statement' and just put cryptotrader.tax there instead for the IRS to reference? I say that because when I filed my return for 2020 and downloaded my 2020 Form 8949 from Cryptotrader.tax, they just had 'cryptotrader.tax' and 'Various' for Date Acquired column. But I e-filed my 2020 return.
