Most tax returns process within 21 days. However, some may take longer. TurboTax does not receive any updates on the status of returns once the IRS accepts them. This means that we can't say for sure why you haven’t received your refund. If it's been longer than 21 days since you e-filed and your return was accepted, you'll have to speak directly to IRS to find out more about the delay. Please click here for more information.
