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 have wash sales, it gets more complicated since those adjusted transactions have to be itemized on Form 8949 and the summary totals adjusted accordingly.

Detail Reporting Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary.
