Trouble amending 1120S 2024 business desktop

I'm trying to amend my 2024 S corporation tax return that was filed with turbotax business desktop.  After following the instructions that I see on the turbotax website, I get a message that says "You have no returns eligible for e-filing."  and it mentions that my return was filed and accepted 2/19/2025, which I already know.  I saved the original return under a different file name.  I have modified the item I want to modify (the employee compensation line).  The turbotax file shows the corrected information that I want to file as an amendment.  But I don't see how to file the amendment.  What could be going wrong?
