No one in the user forum can tell you what time a deposit will post to your account. Those times vary with many banks. You just have to watch your own account.
And....what is "it" that says your refund will be deposited today? Only the IRS is in control.
TurboTax gives you an estimated date for receiving your refund based on a 21 day average from your date of acceptance, but it can take longer. “21 days” is not a promise from TurboTax or the IRS.

How it works
Where's My Refund shows your refund status:
- Return Received – We received your return and are processing it.
- Refund Approved – We approved your refund and are preparing to issue it by the date shown.
- Refund Sent – We sent the refund to your bank or to you in the mail. It may take 5 days for it to show in your bank account or several weeks for your check to arrive in the mail.
