The IRS is not accepting returns until February 12th. Intuit is just holding them until then.

Yes, it is as simple as the Feb 12th date.

Click that red alert button on your toolbar, Intuit sent out an alert that explains how it works.

I filed a Form 1040 on 2/14/2021. It is still stuck on received by Intuit. I just filed a different client's return and it was immediately sent to the IRS. What gives.

That alert applies to returns filed on or before 2/12/2021. What about returns filed after 2/12/2021 which are still in a "received by intuit" hold status. What is Intuit's excuse for the continued hold status of these returns.
