A custodial account is under the child's social security number.
However, since she is your child and dependent, there is a provision for entering it on your return, using form 8814. But, this can only be done if her only income is from interest and dividends.
Because there are no interest or dividends reported on Form 1099-B your daughter will have to report the 1099-B on her own tax return.
