Even though the IRS issues 9 out of 10 tax refunds within 21 days, it's possible your return may require additional review and take longer to process. TurboTax, unfortunately does not receive any updates once the IRS accepts the return.
Continue checking the IRS Where’s My Federal Refund? site for updates. Updates are made daily, usually overnight. You may also download the IRS2Go app to check your Federal refund status.
