Does my daughter need to file if she owns nothing (zero)?

My daughter had a small amount of taxable scholarship (about $2000 over tuition and fees and books and equipment). This is less than the standard deduction of course. So she owes $0. Does she still have to file a return for herself? If not, why doesn't TT say that? At the end of the process for her return it is telling me to go ahead and file but I don't think she needs to. She has no other income (earned or unearned). She does have a 529 and did use some funds to pay for qualified expenses but none of that was taxable. No other income other weird things - just a basic dependent college student :-). Thanks.
