1099Q

I entered the 1099Q (TAP 529)under the recipient (me) and the beneficiary is my son. However, when I entered the education expenses (tuition, room and board) and the 1099Q benefit amount (which is lower than expenses, it still shows me owing tax on it.  I think I read that I do not have to enter the 1099Q at all, is that correct. Or, should I try to get the calculations to work. Not sure why Turbotax still shows me owing tax on it.
