My parents claimed me as a dependent. Should line 10b be 1 on my IL1040?

Its possible.  Here are the Illinois instructions for Line 10b -

Line 10b If someone else can claim you as a dependent and your Illinois base income (Form IL-1040, Line 9, or Schedule NR, Line 46) is $2,175 or less, your number of exemptions is 1. greater than $2,175, your number of exemptions is 0.
