The IRS is not done with your return. They have not approved of your refund yet. Keep waiting and check the refund site.
Note: “Accepted” is not the same as “approved”. TurboTax tells you the e-file was accepted if the IRS deems that there is enough information on the return for them to take it in for processing. Only the IRS can approve of the refund, which is a later stage of processing. If the IRS approves your refund they will provide a date for the refund to be issued.
