Have the same issue. My locality groups are different from the previous reply. Group 1 lists several cities “Aurora, Elgin, Waukegan,...”. Group 2 is “Any other locality that imposes a local sales tax”. Group 3 is Not Applicable. I can choose Group 2 and my sales tax deduction goes up. Why? I already provided a total sales tax rate of 10.25% for Illinois (Chicago) earlier.
