If you answer No and enter nothing in the next section about contributions, TurboTax accepts this and moves on without increasing the tax liability. I just tried it on my mock system and got the same question. I'm sure there is system logic in there regarding you having a family plan that includes her.
If that doesn't work for, you can send me a diagnostic copy of your file as described below.
We can pull up a
sanitized copy (all personal information is blocked from view) of your tax
return and take a look to see if something is triggering the error. Here is
what you need to do to generate the token code:
Open up Tax Tools at the bottom left of the side bar. Click on Tools directly underneath Tax
Tools. Tools Center will pop-up in the
middle of your screen. Select Share My
File with Agent. Click OK for Diagnostic
Copy. The next box will have a six digit
number that you share. (It's a random
number generated number that means nothing to anyone else).
