State tax filing

OK, then that means that the MI-8453 was not used to sign the e-filed return, which means that the guidance you quoted in your first reply is not applicable (because that guidance applies only if the MI-8453 is used to sign the return).  Which gets back to my original question:  why do the TT instructions say that I need to sign the MI-8453 within three days?  Where do I get the form?  What does signing it signify?  What do I do with it after I sign it?   I know you're trying to help, and I appreciate it.  Hopefully you can see how a non-expert would be puzzled when told to sign a form without being told where to get the form, what the form means, and so forth.  Why would TurboTax tell me to sign a form within 3 days without providing any explanation of the form?  I'm still unclear on what to do.
