You can check the status of your return by signing back into TurboTax and you should see your status first thing upon signing in, it will either say e-file or ready to mail for your status. If you do not see your filing status, then you have not yet filed your return and will need to revisit your return and complete the filing process.
Where's My Refund? tool includes a tracker that displays progress through 3 stages: (1) Return Received, (2) Refund Approved, and (3) Refund Sent. It also provides an actual personalized refund date as soon as the IRS processes your tax return and approves your refund.
