How much did you actually gain/lose on crypto?
Assuming all Short Term, this is what you report on Form 8949 Line 2 with Box C checked which copies to Schedule D Line 3.
In 8949 Line 1 you can do a one-line aggregation with "<name of broker>" for description, and dates of 1/1/2021 - 12/31/2021 or Various - 12/31/2021.
You may want to ignore the transaction detail reporting requirement and see if IRS asks for it later.
You can deal with that at that time.
Given the backlog at IRS they probably won't ask for it.
