thanks your request, it didn't say any thing. myself review Fed tax can't find anything wrong. but when I reviewed IL state tax then found :
the state tax form IL-1040 line 3 other additions. Attach schedule M which didn't have any data either.
so no idea how to fix it at all.
however I manually calculated found out :
Resident net income L9-L10 $10624 IL-1040 L11
but turbo tax showed $10574 ie $50 less
I hope it answear your inquired.
ps I also found Schedule ICR (ILL credit) that L3 is empty L5 is $290 but L6 (L5-L3) became $233
