Why did my status move to estimated federal refund date?

Are you seeing this in TurboTax or on the IRS website?

If you're seeing it in TurboTax, the estimated refund date provided is based on the average amount of time it has taken other taxpayers to receive their refunds. Once your return has been accepted by the IRS, TurboTax can no longer provide updates.  The best place for information regarding your tax refund is the IRS Where's My Refund? site. Where's my Refund has the most current information regarding the status of your tax return and will also provide a date of when to expect your refund, once it has been processed. Per the IRS, most refunds are received within 21 days from the time a return has been accepted.
