The IRS Where's My Refund? lookup service provides a specific, personalized date for your tax refund.
The TurboTax Refund Tracker,
on the other hand, projects an estimated date range on when you can
expect your refund, based on other TurboTax customers who have already
received their refunds.
Many different factors can affect the timing of your refund after the IRS
receives your return. Even though they issue most refunds in less than 21
days, it’s possible your refund may take longer.
