I just e-filed my 2021 federal tax return today, then immediately realized it was incorrect. I know that I need to file a paper 1040X. How long should I wait to do so?

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

The federal amended tax return, Form 1040-X, for tax year 2021 is estimated to be available in TurboTax on 02/24/2022

Thanks for the reply. That makes perfect sense.
