How do I know when the 5 days early is up if I don't know the send out day

Look at the IRS Where's My Refund site. It will be 5 days earlier than the date listed there.

You should get an email from TurboTax when your refund is on its way. Some didn't get an email until late in the day, but still got their deposit.

5 Days Early Option

If you don't get your deposit, there is a few reasons why that might happen.

• Your refund was offset or differed from their estimated refund amount, bringing the refund amount below the minimum threshold or above the maximum. What is a refund offset?
• Your bank wouldn't accept RTP (Real Time Payments) or Same Day ACH deposits, preventing Intuit from depositing your refund 5 days ahead of when the IRS would have deposited your refund.
• The IRS didn't give Intuit 5 or more days of notice in advance. This stopped Intuit from meeting the 5 days early expectations.

If TurboTax is unable to deliver the refund 5 days early, your order will be canceled and you won't be charged the 5-Day Early fee. You will receive a follow-up email with a refund and timing update, and if any cancellation is applicable. 

If you don’t receive an update email or an automatic refund (if applicable) within a few days, you can contact TurboTax Customer Support by clicking the link below.
