After you file

the IRS has a huge backlog of returns.  even e-filed returns are taking longer to show up in the IRS system than normal.

when you e-file. the IRS sends the transmitter (in your case Turbotax) notification that it was either accepted or not.  Then Turbotax sends you a corresponding e-mail.  since you seem to be saying that you got an acceptance e-mail, the IRS has it.
