Will my dependent daughter need to file a tax return for money exceeding tuition expenses from a 1098-T? Where does she enter the info since I claim her? She has no W2.

I have already filed my taxes and claimed the 1098-T on my return.  A message on TT stated that she would need to file a tax return to report the taxable income.  She is 19 years of age and does not work and relies on me for support.  Where would she report this income on a tax return?
