Michigan CIT Return will not transmit

I am trying to transmit a 22 Michigan CIT return for a business with FYE 9/30/23.  I initially tried transmitting both the 1120 and the CIT at the same time, multiple times over 30 days.  I would receive the message that the "agency is not accepting e-file at this time".  I spent 2 hours on the phone, mostly on hold, with TT "support"  I talked to multiple levels of support, each time having to explain that there is no "filing window" for corporate returns, and had to show them proof of the fact that I file these two returns at the same time every year for the last 8 years.  The last level 2 or 3 support person I talked to admitted that it was indeed a TT problem, and that in 2 days they would contact me and give further information.  That was a week ago.  So now, what I have is confirmation that it is a TT error, and apparently there is nothing I can do about it.  I tried the day after the phone call to uncheck the Michigan Return, and file the 1120.  It went through and has been accepted.  I still can not get the Michigan Return to transmit.  Michigan requires the return to be e-filed.  Am I going to have to go out and purchase a different product to file this return?  After I specifically paid TT for the Michigan CIT module?  I need some help here please.  Short of spending another 2 hours on the phone to be told that it indeed a TT issue, I am not sure what else to do.  Very disappointing from a product I have been purchasing for over 8yrs.
