TurboTax tells you the return was "accepted." The IRS does not use that word. The IRS tells you that your return is being processed. Until the IRS finishes processing your return you will not receive your refund. You can watch the IRS refund site for updates. TurboTax gets no information after you file your return.
If the IRS site says your return is under review, it means the IRS is taking a closer look at something and you will be waiting for them.
