After you file

The 1040x form is now available; however, when attempting to amend my 2023 return (which was already processed by the IRS), turbo tax says that I did not e file the 1040 with them so I cannot e file the 1040x with them.  This is not the case as I definitely did e file using turbo tax.  I called turbo tax and they had no idea why it wasn't working and said that I did e file my 1040 with them.

 

  Is turbo tax allowing anyone to e file an amended 1040x for 2023 yet, or should I assume this is a problem for just me?
