Reported 1099Q for withdrawal of qualified expenses as recipient for my son's 529 fund via turbotax. Why is this causing increase taxes due on my return?

[scorpiniti]

All withdrawals were paid to me as recipient but for all qualified expenses.  I paid all expenses on behalf of my son and have records.  Why is this causing increase in income tax due?

If the tuition and expenses entered are greater than the distribution from the 1099 Q, the distribution will not be taxable. Make sure you have your education expenses included along with the 1099 Q
