Childrens' AGI

While completing my State return in Turbotax Deluxe desktop, I skipped a question about the amount of my childrens' AGI.  When I went back to input the amounts, I could no longer find the question (I looked thru all forms and attempted going thru the return again).  I have 2 dependent college age kids who each had incomes < $10,000.  Should I worry about not completing this question?  I'm assuming that skipping the question made it appear the amounts were $0.
