Do you have email confirmation of the transmission or acceptance of your return? The IRS updates in 24 -48 hours. You can track via the IRS Where's my Refund tool?
Log into your TurboTax account to view if you completed submission of the return. You can contact TurboTax Support and they can review if the return was submitted and accepted.
Maybe you didn't finish filing or your return rejected.
Did you go all the way to the end and hit the big orange Transmit Returns Now button?

When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile.
When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. what does it say? If it says Ready to Mail that means you are suppose to print and mail your return to the IRS.
