@jimamster This is strictly my opinion, I have no evidence to back it up: I believe it's a bug and when enough people report it, it will be corrected. So far, we have MI, NJ and NY reporting the same issue.
I talked to TurboTax support and they said it was a problem with the forms provided by State of Michigan.
I talked to the State of Michigan (side note, they were very, very helpful) and they said they would contact TurboTax directly because they (TurboTax) are required to provide e-filing for all products they support for Michigan.
In the meantime, I asked the State of Michigan folks if I could file by mail and they said "yes" so I am going to wait a week and see if the issue gets fixed by TurboTax and, if it doesn't, I will e-file.
Best of luck to you!
