since she is your dependent only you are eligible for tax benefits ; the 1098T only goes on your return - not her's.
(in fact, since she'll click the box saying she is a dependent of someone else on HER return, I would expect there to be no impact if you tried to key in the 1098T on her return).
exception: if Box 5 exceeds Box 1, then the 1098T does go on her return and not yours.
