After efiling, normally it will have an efile status of "pending" up to 24-48 hours. However, since the IRS just opened up for processing this week, they have a huge backlog, so a status of "pending" may persist longer. Once the IRS agrees to start processing it, the efile status should change to "accepted". Unless, of course, it is "rejected".
If you used Online TurboTax to prepare the return, you can check the efile status occasionally by logging back into your Online TurboTax account and checking at the Tax Home. You should also be emailed a notification when it is accepted or rejected.
