Hmmmm,  what I did and that may have been what messed me up is I used save as “same name but added original”.  Then I went back to the one that was originally efiled and set up amended return but with all my playing around I have lost the original accepted acknowledgments on the originally efiled return 😩. Have tried to get them back and have gone to various efile logs and return doesn’t show.  As a last resort because I was so frustrated, I tried efiling again and of course it won’t efile because it says it was already done!   Thinking of sending in paper amended but I am stubborn and would like to figure this out and efile.
