If this does not completely answer your question, please contact us again and provide some additional details.
We are having an Ask the Experts event specifically about Crypto transactions on 03/15/23. Please register for it here.
This is contrary to the IRS instructions for how to report Short Sales.
It also doesn't help the situation since every date still has to be modified.
Regarding stock and options, for Box A and Box D, only wash sales have to be itemized on Form 8949.
The other transactions without adjustments can be aggregated. Report the sub-totals of cost and proceeds for those transactions on Schedule D Line 1a or Line 8a respectively.
If you have no wash sales, there will be no form 8949, No attachment is necessary. No mailing is necessary
