Deductions & credits

I understand, but you can't get this error unless you enter data on one certain screen, which you won't see if you (well, she) didn't inherit the HSA.

That's why I suggested just deleting everything and starting over, in case there is some spurious data somewhere that you can no longer see. Of course, if you don't have a W-2, just delete the 1099-SA (if one), the 8889-T, and the 8889-S, and then redo the HSA interview.
