TurboTax does not receive updates from the IRS once they have accepted your tax return. The IRS reports that they issue 9 out of 10 tax refunds within 21 days, it's possible your return may require additional review and take longer to process. Where’s My Refund? has the most up to date information available about your refund. The tool is updated daily (usually overnight) so you will just usually need to check once a day.
For more on the timing of your refund please see this TurboTax FAQ.
