If you have an NOL on the federal return this should carry to MI automatically.

Thanks for the response. I have a 2018 K-1 with positive income allocated to different states. In both 2016 and 2017, my K-1 had a loss. I filed returns for those years in all states and reported the negative income. Is there a way on the TT state return to carry over the reported 2016/17 loss to reduce the positive state income for 2018? I know it is 1040 Schedule 1 Line 21 for MI but don't know how to enter that or if it is even possible. Arizona is 1040NR Line 47. Same scenario there.
