After my purchase went through and I printed my IL state tax return, I realized that the information on the return that I was about to mail to IL was incorrect. I don't have an option to go back through and edit my information anymore but the mistake is causing me to owe IL money when I should likely be paid by IL for the deductions that already came out of my paychecks. I worked in IL for a few months this past summer as a non-resident and didn't make the amount of money that the form says I did.
