incorrect 1099T information

The 1098-T is only an informational document. The numbers on it are not required to be entered onto your tax return. However receipt of a 1098-T frequently means you are either eligible for a tuition credit or possibly your student has taxable scholarship income. 

You claim the tuition credit, or report scholarship income, or claim the 529 plan earnings exclusion,  based on your own financial records, not the 1098-T. In the 1098-T screen, click on the link "What if this is not what I paid the school" underneath box 1. You will then be able to enter the actual amounts paid. 

Better yet, you can just not report the 1099-Q, at all, if your student-beneficiary has sufficient educational expenses, including room & board (even if he lives at home) 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. You would still have to do the math to see if there were enough expenses left over for you to claim the tuition credit. You also cannot count expenses that were paid by tax free scholarships. You cannot double dip! 

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." 

All that said, your 529 plan distribution is technically not qualified.  The distribution must be in the same calendar year as the payment was made.  This is frequent topic, in this forum, and the consensus seems to be: claim it anyway, as you certainly meet the intent of the rules and hope the IRS accepts your explanation in case of an inquiry.  Do a better job, next year, on matching. 

You can enter the 1098-T exactly as printed. Then later screens will ask you for additional information and costs that were not included on the 1098-T.  Do note that it's up to you to keep track of this stuff so that you don't double-dip next year, if they include what you added on your 2021 tax return, to your 2022 1098-T.
