She might be better off filing her own return and getting a refund.
Also, depending on what your daughter earned, she may be required to file.

"All taxpayers who are claimed as a dependent on someone's tax return are subject to different IRS filing requirements, regardless of whether they are children or adults. Since a dependent is unable to claim their own exemption, a tax return is necessary when their earned income is more than the standard deduction for a single taxpayer, which in 2016 is $6,300. However, the threshold decreases to more than $1,050 when the dependent's income is unearned, such as from dividends and interest."
