I guess I found my answer on the IRS website (in the instructions for Schedule D): Lines 1a and 8a— Transactions Not Reported on Form 8949
You can report on line 1a (for short-term transactions) or line 8a (for long-term transactions) the aggregate totals from any transactions (except sales of collectibles) for which:
You received a Form 1099-B (or substitute statement) that shows basis was reported to the IRS and doesn't show any adjustments in box 1f or 1g;
The Ordinary box in box 2 isn’t checked; and
You don't need to make any adjustments to the basis or type of gain or loss reported on Form 1099-B (or substitute statement), or to your gain or loss.
If you choose to report these transactions on lines 1a and 8a, don't report them on Form 8949. You don't need to attach a statement to explain the entries on lines 1a and 8a and, if you e-file your return, you don't need to file Form 8453.
