TurboTax never says your refund was "approved." TurboTax tells you the return was "accepted"---do not confuse those two words--they do not mean the same thing.

Only the IRS can give "approval" of your refund, and it seems they have not yet approved it. TurboTax gets no information after you file your return and the IRS accepts it for processing. Only the IRS is in control now. Your information will only come from the IRS. Frustrating as it is, you have to wait for the IRS. If you want to contact them you can.
To call the IRS:IRS: 800-829-1040 hours 7 AM - 7 PM local time Mon-Fri
