When amending on paper,
do not include your old 1040 nor your revised 1040 because the Form 1040-X reflects any changes there and becomes your new tax return.
"How about 1040x?"
1040-X is your amendment. you must sign it.
Note: when you are not changing any dollar amounts on your amended tax return, you can leave all the lines 1-23 EMPTY.
Part III Explanation " I neglected to report Code G rollover on Line 5 (or Line 4). taxable amount zero".
It will take the IRS at least six months to process a paper Form 1040-X.

P.S. IRS knows what Code G is so the whole exercise is unnecessary.
