Your response solved my problem and I thank you for that!
However, I have needed this form every year for quite a few years, and this is the first time I have had any difficulty finding it. Last year, it was found by starting on the page with the heading "Here's the income that Illinois handles differently", then going to the sub-section "Exempt Interest Income". This year, that sub-section is not listed.
For the benefit of other users who need this form, I hope you will fix this soon in a program update.
