After you file

@Johngereshenski65 Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund

 

What you are seeing is an Estimate Only based on the IRS target of 21 days to send a refund after receiving the tax return.  This is Not a guarantee.

 

If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

 

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
