In ProSeries Basic, if I open a filed return that had reported full unemployment without the $10,200 exclusion, the return is automatically adjusted to show the reduced AGI.  At that point I can't tell what the original amounts were that was filed.  And then to open up the state (MI), I can't create an amended return because the state return AGI has already changed (reduced), I don't have a before and after scenario to create a MI1040X.
