Details Reporting Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary.
You can trim those details out of your mailed report.
If you don't have a 1099-B for crypto your sales category is C or F.
There is no exception for these categories.
I don't think anybody is going to mail in such a huge document,

They're too busy at the moment.
IRS hasn't even figured how to enforce crypto reporting yet.
