State tax filing

I would like to report that the Illinois State Schedule ICR form in TurboTax is working correctly.  I spent a bunch of time filing in the IL-1040 and Schedule ICR forms with various values and determined that Line 5 of the ICR does indeed work as it should.  I needed to read carefully the Ilinois Tax Instructions while filing out the tax forms and noticed that there are a number of Exceptions which affect the results.  You cannot rely on just the instructions on the forms, and the forms do not infer that there could be exceptions.  TurboTax's programming of the cells did take into account these Exceptions.  Thank you for all of your time and assistance on this issue.
