Do you mean Refund Advance or your federal tax refund?

Concerning a Refund Advance:
Once your Federal Return has been approved by the IRS, you should get an email from Turbo Tax that will go over information concerning your “virtual card” with the refund advance. Once the steps in the email have been completed, you should receive your funds in about 48 hours. Please see the below link for additional information:
