2021 Amended Taxes

I submitted my Son's Admended Taxes on March 20, 2022 (I forgot to check the box to state he was dependent on me).  When I check the status of the taxes it continues to say it has not been processed and when I call the IRS I cannot ever talk to anyone.  Also, since My Sons Taxes are not completed I cannot get my refund on my IRS and NC taxes ($4,000).  Do you have any idea on what is going on?
