When TurboTax website shows "accepted", that only refers to the efile status. It means the IRS accepted your return to begin processing it. That status will not change in TurboTax. It does not refer to the status of your return's processing at the IRS. Go by the IRS website.
The IRS does not use the term "accepted" on it's website tool. It has 3 stages:
Return received and is processing
Refund approved
Refund sent and expected date provided
