I dont know why it tells you to make a copy, its wrong, you dont need program data file for it. Print a copy or save to PDF, then just use the client computer file you EF originally.

Open the original file and activate the 1040X (CTRL + F type X and it will pop up in the list of forms), mark the year box at the top to "activate" it.

Now go over to the state return (if applicable) and activate its amended form.

Now go back to the federal and make the changes, type the explanation of changes on the 1040X, go to the Federal Info Worksheet and mark the EF box for Amended return.

Now go to the EF PIN date box and enter todays date (it will still have the date from the original EFing, you need to change that or it will reject)

Then go over to the state return and make sure its amended return is completed as well.

Save and exit to the EFCenter and you should see the client file in the Pending Tab with the return type as Federal Amended, highlight it and hit the EFNow button on the toolbar...I usually Convert alone to make sure the file will convert, then I go back and Transmit, but you can do both at once.
