The IRS will not begin to accept/reject returns until January 28. Until then, e-filed returns will just be sitting on a server, waiting. You will receive an email after that date letting you know if your return was accepted or rejected. It will probably take several days after January 28 for them to work through the backlog of returns on the server.
Lots of people are gettin accepted but nothing is processing until the 28th. Regardless of when processing begins or hoe early you file, it’s neber taken over 48 hours to get accepted before. I filed 5 days ago and still pending as well.
You'll see reports in this forum of some number of users getting their efiled returns accepted early. But the forum is not a cross section of TurboTax filers. Most online forum users have an issue they are seeking answers to. Most TurboTax users do not need to visit the forum. Millions of people use TurboTax each year.
Every year the IRS pulls "some" returns early for testing purposes. The vast majority of early filers will have to wait until the IRS officially opens up on January 28 to find out if their return is rejected/accepted. AND even then, not all the pending returns can be acted on during that one day, so it may be 24-48 hours or so after January 28, before many will get a result.
There's no way to predict if your return will be pulled early or not. But at this time of year, it would be normal for most people to have to wait until January 28.
