Accepted does not mean Approved.
Accepted only means the IRS verified some basic info on it so they know it's really from you. After it is Accepted the IRS processes it then approves it before they send the refund.
The IRS is taking longer this year because of Covid-19. Only the IRS can tell you when you get it. IRS Where's my refund

Make sure you are using the refund amount from your actual federal tax return and not the combined amount Turbo Tax showed you at the end. That was for federal and state combined.
