Input of 529 tax-free withdrawals to pay student loans?

Hi there.

I have both qualified education expenses and qualified loan repayments that I made from a 529 in 2023. 

I can't figure out how to get Turbo tax to not make me pay tax on the qualified loan repayment.  No matter what I try, the loan amount will not show up on page 3, line 2a of the 1099-Q worksheet and so Turbo tax is making me pay unnecessary tax.
