There is a question in the HSA interview that asks "Did [name] inherit this HSA?" You won't get this question about the qualified medical expenses and the FMV unless you say "yes" to the question. Note that according to the message you posted, this occurred on your spouse's HSA.
Also, there are two distribution codes in the 1099-SA that the distribution was an inheritance. The code is normally "1" (normal distribution). Perhaps they will trigger the same question about medical expenses.
Go back to the HSA interview and review your answers. If you cannot figure out what happened (or TurboTax refuses to forget something so still thinks you had an inheritance), then do the following:
The safest - although brute force - way to fix this is to do the following in this order:
1. make a copy of your W-2(s) (if you don't have the paper copies)
2. delete your W-2(s) (use the garbage can icon next to the W-2(s) on the Income screen
*** Desktop***
3. go to View (at the top), choose Forms, and select the desired form. Note the Delete Form button at the bottom of the screen.
*** Online ***
3. go to Tax Tools (on the left), and navigate to Tools->Delete a form
4. delete form(s) 1099-SA (if one), 8889-T, and 8889-S (if one)
5. go back and re-add your W-2(s), preferably adding them manually
6. go back and redo the entire HSA interview.
