Since your transactions are all covered transaction,
The correct solution is to use aggregation aka enter a summary.
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.
Enter the wash sales on Form 8949, then use the subtotal results on the bottom of that form (Line 2) to know how much to subtract from consolidated 1099-B which gives you the Schedule D line 1a totals. Be sure to NOT check the adjustments box in the summary window.
