I was able to deduct 529 plan(IL) contributions on behalf of my son for the 2017 year. I can't find it for the state of IL this year. Where is it for 2018?

In Illinois under Income, you will come upon a page entitled "Here's the income that Illinois handles differently". Under Education, it is the first item: College savings and prepaid tuition plan contributions.
