In this situation, TurboTax gets conflicting information (not your fault). You have to report "None" as your HDHP coverage, yet line 1 of form 8889 does not allow "None" as a coverage option (or else why are you filing 8889?).
In your case, please see the following:
In the Review, you may get new errors. If you do, this is how you address them:
1. If the Review asks you to check a box on Line 1 of form 8889, go ahead and check "Self" (It won't matter, but it will help get you clear of the Review).
2. If the Review asks you to check a box in the Line 3 Smart Worksheet of form 8889, go ahead and check "None" for A1 through A12 (i.e., each month).
2. If the Review asks you to check a box in the Line 18 Smart Worksheet of form 8889, go ahead and check "None" for B1 through B12 (i.e., each month).
This should clear the form 8889 errors and let you e-file.
