It is possible to accidentally indicate to TurboTax that you have an HSA, when perhaps you didn't. If you didn't have an HSA in 2018, please do the following to remove all traces of HSA data from your return:
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. continue with your return.
NOTE: if you see a question asking about your HDHP coverage on December 1, 2017, answer "NONE" and continue.
