Can you still use the EIC lookback if you have already e-filed your 2021 taxes?? And the IRS accepted it within 15 mins

Did I supposed to use the EIC lookback link before I e-filed my 2021 taxes?? It seems I can't go back to compare

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, or to amend if a TurboTax update changes your return or for any other reason,

AND, to find your AGI next year.

Once your return is ACCEPTED by IRS, that's it.

Use Form 1040-X to add or correct information on an already filed tax return.
