After you file

No, as I said above  after you delete  the 1040X you have to manually take out the changes and put your return back to the way it was when you originally filed it.  If you don't remember what you changed you will have to look at a copy of your real return to see what is different now.  Then when each line is the same as you originally filed you can amend.   You can use the Forms mode to put your return back.
