@roytoutant - sorry I can't help any much further - a few ireas
1) if you change those 'errant' sales so they are also reported on 8949 forms, then you will have the flexibility of adjusting them so they are not reporting in Michigan. As long as it does NOT change the Federal tax return (and it shouldn't - just be careful it doesn't) , I frankly don't see the issue.
2) contact customer support line and ask them what to do ...... it has to be a setting somewhere.
