@elcabrera what is the problem? Did you claim her on your return? You can claim her. If you filed first your return should be ok. If she tried to claim herself then her return would reject. She needs to check the box saying she is claimed as a dependent on your return. So if her return went through she needs to amend.
What is saying your return is wrong? Did your efile reject? You may have to print and mail it.
