I normally file as Head of Household. Have one child that is currently 17. Last year, I entered $2000 in step 3 for qualifying children under 17(when they were 16) and forgot to change it once my child turned 17, thus owing a large tax penalty. This year, should I enter anything in, for section 3? I currently have $500 entered for “other” dependents. Section 4 is currently blank. Should I just leave the section 3 blank?
