If you want or need the original tax data file you might be able to get it back. You are using the Desktop program? First make a copy of your amended return with another name File-SAVE AS
Then......
1. Open your return
2. Switch to Forms Mode
3. In the left pane, select Form 1040X
Windows: After the form is generated in the right pane, select the Delete Form button at the bottom of the window
Mac: From the Forms menu, select Remove Form 1040X
4. Follow the on-screen instructions to remove the 1040X from your return
5. Switch back to interview mode by selecting Step-by-Step in the upper right corner (Windows) or EasyStep in the upper left corner (Mac)
6. Important: Undo any changes you made to your return after you selected the option to amend your return, as deleting your 1040X won't undo those entries
