My daughter didn’t check that she could be claimed as dependent on her tax return. She then ammended her return to fix it but my tax return is still getting rejected

The rejection is still saying my dependent didn’t check this box even though she amended it with box checked. What do I do from here? I am assuming the amended return takes awhile to register in the system but meanwhile mine won’t get accepted. I tried calling the IRS and you cannot get a live person to answer questions!
