Once your return is accepted, TurboTax does not get any other information about the processing of your return or refund.  Only the IRS  would know why you have not received your refund. 

All you can do now is keep checking the IRS website, Where's My Refund, for your Federal information.  The website updates once a day.

You can also try calling the IRS.

The IRS telephone number is 1-800-829-1040, and they are available from 7 a.m. – 7 p.m. Monday thru Friday. The best time to call is early in the morning.

- Next, press 3 “for all other questions.”
-Next, press 2 “for all other questions.”
