I filed my taxes on 2/12, but they are still saying pending. In the past years it was accepted within 24 hours, both state and federal. But it’s been a week now.

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.   There are a LOT of returns on all the servers so it may take several days even after the IRS opens up before you get an email.

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.
