If your daughter starts using her own account, she won’t be able to access any returns in your account, even if the returns are for herself. So, she will not be able to transfer her information from last year.
You can still print or download a PDF copy of her returns to give her for reference. Please see this TurboTax FAQ for instructions: In the online edition of TurboTax, how do I print a copy of my tax return?
