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.
If you provide all details of all wash sales on your e-Filed return, no mailing is necessary.
