I am e filing, but I need to attach an Indiana tax form to my Michigan return (I'm from Michigan). How do I do this when e filing?

Is there a way to attach a PDF to the e-file, or is there some other way to get this form to Michigan?

No.  You cannot attach a pdf to your electronic filing for Michigan.

Unless instructed otherwise, TurboTax will include all forms needed when electronically filing your Michigan return. If additional forms need to be submitted, TurboTax will provide you with instructions to mail the additional information in.

I just found out it costs $20 to file to state anyway. Rather spend  a $1 on stamps. 
Can't get Fed to go through even thought the pin numbers and AIG match, so mail it is :(
