TurboTax would not think that you had an HSA unless you had either a code "W" in box 12 of your W-2 or you had a 1099-SA.
The first shows contributions to your HSA and the second show distributions from your HSA.
If you had one of these, you need to talk to your employer to find out why they are reporting this when you don't have an HSA.
It sounds like you may have an FSA (Flexible Spending Account) instead.
If you have an FSA instead of an HSA, do the following:
Delete the 8889 form and related forms. Do this by going to My Account (at the top), click on Tools, then on Delete a Form.
Delete any "Form 1099-SA" you see, as well as any "Form 8889-T" and "Form 8889-S".
NOTE: you do not enter anything related to your FSA into TurboTax.
