If your returns have been accepted, then TurboTax does not get any information about the processing of your return or refund. Only the IRS & State would know. The IRS is closed & they are not taking phone calls. They are still processing e-filed returns & stimulus checks but they have been behind.
It is taking the IRS longer to process returns since they are closed. They are still processing e-filed returns but the 21 days (business days) is not the standard now due to Covid-19. The IRS is not processing mailed in returns at this time.
All you can do now is keep checking the IRS website, Where's My Refund, the website updates once a day.
