Tax help for military filers

HELP!  I have military pay from the Guard and live in Illinois.  The W-2 is entered, and military information provided for federal return.  TurboTax transferred all the data to file my state return; however, the computer system has “determined” I am not eligible for the military pay exclusion,  which is WRONG ( and stated here).  How do I override your system to get it deducted from my Illinois return?????
