No one here can tell you what time of the day a refund will be posted to your account. It also depends on whether you chose to have TurboTax fees deducted from your federal refund. If so, it goes through a third party bank and can take a few extra days to post to your account. From the time the IRS releases the refund it can take several days to post to your bank account. Once the return has been accepted by the IRS, TurboTax gets no further updates and cannot tell you when your refund will actually arrive.
