It appears that you are trying to claim a loan payment as a qualified expense for a 529 distribution (as opposed to claiming the student loan interest deduction). That is allowed, under the Covid Relief law. There is a $10,000 lifetime limit, per student.
You do not need a 1098-E to make that entry in TurboTax (TT). Making a payment on the beneficiary's loan (or the beneficiary's sibling's loan) counts. The $10K limit applies to each sibling.
Follow the interview carefully. Click continue at the 1099-Q summary page. You will eventually reach a screen to enter the loan info.
Better yet, just don't enter the 1099-Q.
You can just not report the 1099-Q, at all, if your beneficiary has sufficient educational expenses, including student loan payments to cover the distribution. When the box 1 amount on form 1099-Q is fully covered by expenses, TurboTax will enter nothing about the 1099-Q on the actual tax forms. But, it will prepare a 1099-Q worksheet for your records.
On form 1099-Q, instructions to the recipient reads: "Nontaxable distributions from CESAs and QTPs are not required to be reported on your income tax return. You must determine the taxability of any distribution."
