The reciprocal agreement does not apply since you are working remotely. It also doesn't apply for part year residents.
On you part year IN return, you claim a refund of both the state and country tax withheld after the move.
If you had physically worked in IN, after the move, the MI credit for county tax would be correct. But. in your case it is not.
@Michiganma said " The spouse's income was 100% from IN, taxed all 12 months IN"
That's not correct. The remote work is not considered IN source income.
