@alimachuca As an alternative to having to reconstruct your 1040 as originally prepared, you could do the following. The form 1040 that currently exists in your file should be accurate because it has the changes you made to correct the 1040 tax return the IRS didn't get. Just print the 1040 that's in your file, send it to the IRS at the address they told you, and instruct them to destroy the 1040X since it is no longer needed.
If you prefer to recreate your original return as you prepared it originally, you may be able to undo the amended return and then make the changes to the return in your file to take out the changes you made for the amended return. After undoing the amended return, you must change the return back to where it was originally. This is instead of completely starting over. Here are the undo instructions: <a rel="nofollow" target="_blank" href="
