If you used the CD program then the return was saved on the computer you used or any backup files you kept. Open the program to open all returns completed using that program.
The tag below your question says you are using TurboTax Online. Did you do your daughter's tax return with TurboTax Online in your browser, or with the TurboTax CD software installed on your computer? What do you mean by "under my turbo tax"?
A TurboTax Online account can only be used for one tax return. To do a tax return for a different person you have to use a separate online account.
If you used the CD software, you should have saved each tax return with a different file name.
