Thank you for your detailed response but it is not pertinent to my situation. I filed my daughter's taxes, checking the box "I can be claimed as a Dependent by Someone Else." She made $2944 from a part time summer job and was a full time student, living with her parents and we paid all of her support. The IRS processed her return and she got back all withholdings from Fed & State. BUT for some unknown reason, the IRS ignored the "I can be claimed ..." box I checked and says she claimed herself as a Personal Exemption (verified by getting a copy of her Tax Transcript).
Therefore when I filed our taxes and claimed her as a dependent, our taxes were rejected since the IRS says she already claimed herself.
I can't Amend her taxes as there is nothing to amend. Her taxes as originally submitted and as amended are identical. It appears to me it is a processing error by the IRS but of course you can't get a hold of them due to the pandemic. Very frustrating especially since I have a $4000 refund being held up due to the IRS's processing error.
