1040-X replaces 1040 and becomes your new tax return.
Always print a copy of your completed tax return for your records, and review it carefully before e-Filing.
You will need it if you are audited by the IRS, to contact the IRS, or to amend if a TurboTax update changes your return or for any other reason,
AND, to find your AGI next year.
OR, to verify refund and amount you owe are zero when you are not changing any dollar amounts on your1040-X.
This goes for state returns as well as federal.
