https://ttlc.intuit.com/community/after-you-file/discussion/amend-a-return/01/2550615#M633569 <P>I am an idiot. I used Turbo Tax Business to file my 2021 company return. I e-filed and it was accepted. Now...I discovered a significant mistake I made and need to file an amendment. I am doing what the program says to do when I start up the program but after I saved the original with a new name as it says to do I get all the way through the process and it says I cannot e-file because I already have an accepted return. What am I doing wrong?</P> Mon, 09 Mar 2026 09:02:21 GMT bobert1 2026-03-09T09:02:21Z https://ttlc.intuit.com/community/after-you-file/discussion/amend-a-return/01/2550615#M633569 <P>I am an idiot.
