You may exclude your actual cost or the school's aid allowance, which ever is less. You may need to check with your child’s school to learn the room and board allowance for students living at home with parents. It’s likely to be less than off-campus students living independently. It's frequently available at the school's web site. The student must be half time or more.
Lacking a published "cost of attendance", you may use what on campus students pay for Room & Board.
