After you file

@bap2 You are posting to a two year old thread.  No wonder no one paid any attention to it.  However, the answer below is still correct--if your return was accepted, then only the IRS has any information.  TurboTax does not know what the IRS is doing with your refund.  You can only track it on the IRS site.  You have to enter your SSN, your filing status and the exact refund amount from line 20a of your 2018 Form 1040 to track your federal refund.
