This is TurboTax 2023 not online, and I don't use the download stuff either (so it's a very simple case); the only Schedule D stuff is from 1099-B and I entered all the 8949 information correctly for boxes C and F. When 8543 (or whatever the number is) popped up on the printed return I experimented by removing all Schedule D information (so all the 8949 went; it's auto-generated) but it was still there.
Clearly a bug.
I had hoped the March 13 update would fix it but it didn't; no response to my bug report for 13 days!
