You and millions of other filed before the IRS opened on 1/26 to start accepting and rejecting e-files. It may take several days for the IRS to clear out the backlog of e-files. Watch your emails.
When you e-file your return you will get two emails from TurboTax. The first one will say your return has been transmitted; the second one will tell you the IRS has accepted or rejected your federal e-file. If you filed a state return, there will be a third email (usually a day or two later) that tells you if the state e-file was accepted or rejected.
