Even though you entered the 1098-T, on your return, it can also be entered on her return. On her return, you will eventually reach a screen "amount used to claim the education credit" (or similar wording). If TT has not prepopulated that with $4000, you should enter (or change to) $4000 (assuming $4000 is the amount you used to claim the credit on your return).
But, if you have done the calculations and know that she still has sufficient expenses (including R&B), after you use $4000 of tuition for the credit, then just don't enter the 1099-Q or the 1098-T.
The 1099-Q and the 1098-T are only informational documents. The numbers on them are not required to be entered onto your (or your student's) tax return.
