My original e-file was rejected because the other parent accidentally claimed part of a childcare credit that should have only been claimed by me since I am claiming the child as my dependent. Since the rejection was due to the childcare credit Turbo said I needed to print in and mail my form. It wasn't actually amended on my side but my partner had to file a 1040X to delete the credit she accidentally claimed.....funny thing is her 1040X, along with the payment that was needed, was processed and the payment cashed over a month ago.
