Tax Year Prior to 2020: Filing MI State return

So my federal return went through no problem on the first, but I was informed that I would have to wait until the 6th to file my MI State return due to something to do with home heating credit? It’s the first year they gave me that option which did give me some extra income, but I’m confused as to what I do now that it’s the 6th. Will they take care of that state return themselves since I inputted all my info, or do I need to keep an eye out for something in me email and/or on TurboTax?
