After you file

I have saved the original 1120-S file as a different .tax2022 file.  Checked the Amended box. But the file shows as Return Accepted and it won't allow me to submit for e-File.  Is there away to clear the new .tax2022 file efile status?  I created a completely new.tax2022 file and reentered the data.  When attempting to efile the new return, clicking the orange button comes back with a message saying there is already a return submitted with the same EIN.  I have 4 days to resubmit as "superseding" before the March 15th deadline.  If I can't get an answer that works, I guess I'll submit it by paper as Amended.  IRS still says if we efile the first return, must efile the second return.  Any suggestions?
