I spoke with an accountant yesterday and he told me that the reason this is happening is that Connecticut made a slight change to one of the pages of the 1040 form. It involves pensions, so if you had any income related to them, you're going to be getting this error. He said that everything should be set by February 21st at the latest and there shouldn't be any problems filing the state return through TT by then. Even if you don't have pension income, you could still end up getting hit by the same issue. He says he's not been able to file any state returns yet for the same reason.
