My return was accepted today. I applied and was accepted for a refund advance. All of the other questions say I should have gotten my advance. But I haven't. When will I?

Once the IRS accepts your return. one hour later, you will get the card info (which then has to be set up with an online account). Forty-eight hours after acceptance, there is money available on the virtual card.

About receiving your Refund Advance

So if you get a temp card number/actual card in the mail, does that mean you were approved for the advance? I haven’t received a notice email if I was denied or approved- just what I was told during the application check out process. My return was accept by the IRS 4 hours ago.
