529 distribution

I paid for room and board for my non-dependent child who is attending college and I got reimbursed from their 529 plan. The 1099-Q is in my name and it showed the reimbursement that I received (and box 6 showed that the recipient is not the designated beneficiary). I entered the amount from the 1099-Q into Turbo Tax for my tax return and I indicated that the beneficiary was "someone else".  Then I entered the same amount as room and board expenses in my child's name. However, turbo tax is still calculating income tax on some of the reimbursement. How do I fix this as this should have no impact on my taxes owed?
