TurboTax does not receive any updates from the IRS once they have accepted your return. You can track your refund with the IRS Where’s My Refund link https://www.irs.gov/refunds/.
The IRS issues more than 9 out of 10 refunds in less than 21 days. However, it’s possible your tax return may require additional review and take longer. Where’s My Refund? has the most up to date information available about your refund. The tool is updated daily so you don’t need to check more often.
