In past years, I've filed for my daughter. Now, she will do her tax return. Can she set up her own TurboTax Account, but access the info from other years from my account?

If your daughter prepares her return in her own account, she won't be able to access her previous returns. They are attached to your account and can't be moved to another account.

You can still print or download a PDF copy of her TurboTax Online returns for her reference. Please see this TurboTax FAQ for instructions: In the online edition of TurboTax, how do I print a copy of my tax return?
