It depends.
First the tuition you "paid off" must have been tuition for 2025. If it was for 2024 or earlier it is not a qualified expense for the AOC.
No, you can not us tax free "grant money" to claim the AOC. Furthermore, you can not "double dip" on tax benefits. That is, you cannot use the same amount of tuition to claim the AOC and also claim the grant to be tax free. But, declaring the grant to be partially taxable, to free up more tuition for the AOC, is usually an option.
But, you do not need a revised 1098-T to claim the AOC (generally, schools seldom issue corrected 1098-Ts).
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.
If you claim the tuition credit, you do need to report that you got one.
You claim the tuition credit, or report scholarship income, 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. You will also reach a screen that allows you to adjust the scholarship amount for "amounts not awarded for 2025 expenses".
Or if you find it easier, just change the numbers in boxes 1& 5 to what your records show. The 1098-T that you enter in TT is not sent to the IRS.
