The form 8889-S is the TurboTax name for the 8889 for your spouse (each taxpayer with an HSA gets a form 8889 - 8889-T is for the primary taxpayer). Note that you don't receive a form 8889, but TurboTax generates one for each taxpayer that has an HSA.
Somehow you indicated to TurboTax that your spouse had an HSA. This could have been to a code W in box 12 of his/her W-2 (which means that he/she does have an HSA) or it could have been because you checked (however briefly) the HSA for your spouse in the first screen of the HSA interview (Federal->Deductions & Credits->Medical->HSA, MSA Contributions).
Note that TurboTax may create a 8889-S as a worksheet, even if it turns out that your spouse doesn't need one - the form will not be printed or send to the IRS in this case. But it shouldn't cause an error message, either.
If your spouse does not have a code W in box 12 of the W-2 (this indicates that the employer is contributing to the HSA) nor has a 1099-SA, then you should delete your HSA content and start over. Please do the following:
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.
