You NEVER send the new 1040 ... column C of the 1040X reflects the information on the corrected 1040. However if you do send the unneeded 1040 the IRS will just toss it in the circular file.
The program presents the updated 1040 for your use to explain the changes that were made on page 2 of the 1040X and so that you can see if you made all the correct changes. It is not meant to go to the IRS.
