I am having the same issue, with the completely unhelpful error message: "You Cannot E-file These Returns. This return has certain forms that can't be e-filed, usually because of tax regulations, so you'll need to print and file by mail. For more details, select the Review tab, above, and continue through Final Review. To file by mail, select the File tab, continue, and select File by Mail."
This message is close to useless, because how am I supposed to know which form is generating the error? I have all the same forms that I have every year, nothing new, and I have always e-filed without issue. I do have a W-2 with Box 16 > Box 1 because of the way CA treats HSA contributions, but again this is true every year. I have updated the software and the forms. The advice above about repeating "Review" gives no new information.
I am suspecting a TurboTax error, not a real issue with my forms. But with such a vague error message, what can I do?
