Does it mean IRS approved my refund with this email saying “Hooray! Your refund is coming soon” Thanks

TurboTax doesn’t know if the IRS has accepted your return after processing and gets no information about your return. The email reflects what happens most of the time but is no guarantee. 

See what is displayed at the IRS "Where's My Refund" lookup tool.

Does it show that the refund has been approved and sent?
