Are you getting the reject on your own tax return, claiming your daughter as a dependent, or are you getting it on your daughter's tax return? What is the exact reject code and message that you got? Does it say that your daughter was already claimed as a dependent, or does it say that a tax return has already been filed with your daughter's Social Security number as the taxpayer?
If you are trying to file a tax return for your daughter, could she have filed a tax return for herself, or could someone else have filed for her?
