I found a 2020 tax year thread for you regarding Michigan.
It was answered by a Turbo Tax "employee - tax expert"
The question was "does TT generate a schedule W?"
TT's response was this in italics and I boldfaced and underlined the important part:
Yes. The information which pulls into the Schedule W, Michigan Withholding Tax Statement comes from your input in the federal interview section. (eg. W-2 Forms, 1099-R Forms, etc.)
The Michigan Schedule W is not supported for electronic filing though.
You will need to print and mail your return.
You will see Schedule W when you print out your return.
