I, too, ran into this problem. Guessing many, MANY Iowa taxpayers are, too.
This is idiotic. You'd think the process would tell us WHERE the problem is but, it doesn't. It throws a form in the window which appears to be unrelated to the error.
The ONLY reason I came to TurboTax this year is because H & R Block's Iowa software is a cluster****. Apparently, TurboTax is just a different kind of cluster****. Neither one leaves me with any confidence that either is better than the other.
