You probably claimed her as your Qualifying Child for Head of Household, and this is OK. If you entered that she lived with you over 6 months, you probably got the Earned Income Credit, which is the largest credit for children (larger than claiming her as a Dependent).
Did your girl have higher income than you? The one with the highest income claims Head of Household. Remember, you don't 'get' $2,000 just for claiming a Dependent.
Open your return and look at it. See if you got the Earned Income Credit. If you did, then don't Amend. It takes weeks to process, and you will have to pay back part of your refund with the Amended Return.
Also, your girl WILL NOT BE ABLE TO EFILE; she will have to mail in her return. She can Efile as Single, and claim your daughter as her Dependent, for the Child Tax Credit.
That way, between both of you, you will have received all the child credits.
