Yes.  If you filed a return last year and weren’t able to claim your daughter because someone else had already claimed her, you should file an amended return claiming her, as long as you’re entitled to claim her.

When the IRS receives a return with you or your dependent's SSN, the IRS system won't allow a later eFiled return with the same SSN, even when you or your dependent are the real owner of the number.

Please see the TurboTax Help article How to amend (change or correct) a return you already filed for instruction on how to amend your previously-filed tax return, and How do I print and mail my return in TurboTax Online? for guidance in mailing your return.
