Lived in Wisconsin and sold Michigan property in 2018. State of Wisconsin is applying capital gain information from Michigan. Is this correct or should it only be on federal and Michigan state form?
That is correct, but you will almost certainly be able to get a credit for taxes paid to the State of Michigan on your Wisconsin income tax return (see below).
This is the primary rationale for preparing a state income return for a non-resident state first (so you know the amount of tax paid to input on your income tax return for your state of residence). Also note that you may have to enter the amount of tax paid to Michigan on your Wisconsin income tax return manually.
