I claimed I did not receive my stimulus on 2020 tax return but have since received it. Federal return accepted by Turbo but not IRS. What do I do?

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.

If you filed, it is like dropping it into a mailbox - you cannot get it back, even if it's pending.

You'll have to wait until your return is either accepted or rejected when the IRS starts processing returns on February 12.

• If rejected, you can make any necessary changes regarding your stimulus payments.
• If accepted, you'll need to amend your return. 
• To avoid unnecessary delays, do not amend until your original return has been fully processed.  You will need to print and mail the amendment.  
• Allow 16 weeks for processing.

See this TurboTax FAQ for help with amending.

It is possible the IRS will process your return without rejecting it, in which case if you cash your stimulus check they will know and should automatically adjust your Rebate Recovery Credit, but it's impossible to know for sure at this point though.
