TurboTax has no possible way to know if the IRS received information about possible fraud regarding marketplace insurance for you.  The IRS does not share such information with TT.   Did you receive a 1095A for the insurance from healthcare.gov?   

You posted your question from online "Live"--have to talked to your tax expert about this?

 You can arrange for the Live help you are paying the extra fee for with your questions from 5 a.m. to 5 p.m. Pacific time.

suggest contacting Turbo Tax to see if they have a workaround.

The problem is that when you efile, it is going to reject since the IRS is expecting your tax return to have form 1095-a included.

otherwise, just paper file 

there is rampant fraud going on - I've seen many, many cases of it.  TaxSlayer has a workaround, but I am not aware of the Turbo Tax workaround.
