Look at all your tax form and attach the forms that have IL taxes taken out. On your W2, if you see IL in box 15 or somewhere in the boxes after that, IL wages in box 16 and IL withholding in box 17, you will include a copy of that form with your IL tax return. For a 1099-MISC, if there's any state withholding, you will see it in boxes 16 and 17. For all other forms, look for boxes that have state withheld and if the state says IL, you will attach the copies with IL withholding to the IL tax return.
Since you live in MI, it's highly probable that only your W2 has IL withholding but check all the forms.
