Will my refund automatically be adjusted if I claimed the recovery credit on my 2020 taxes and now I received the second stimulus check?

MY RETURN IS IN PENDING—what does that mean?

Did you e-file?  Did you click that big orange button that said “Transmit my returns now?”  If so, your return is now in “pending” on a server.  Do not try to change anything while your return is in pending. If your return is rejected you will be able to make corrections before re-filing.

The IRS will not be accepting/rejecting 2020 returns until Friday, February 12, 2021.  You need to watch your emails for the acceptance/rejection notice that may take until mid-February or later to arrive.   And watch your spam folder too.

When you e-file your federal return you will receive two emails from TurboTax.  The first one will say that your return was submitted.  The second email will tell you if your federal return was accepted or rejected.  If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.

A state return cannot be accepted until the federal return has been accepted.

We do not know if entering the wrong stimulus amount will delay your refund --- or for how long if it does.   The IRS has not offered any guidance yet on how they will handle returns that have incorrect stimulus amounts entered.  We all just have to wait and see.
