Refund Advance - Haven't Received

I applied for, and was approved for a refund advance. I then got my approval notice from the IRS that my federal refund was approved. On TurboTax it also shows that my federal refund was approved. That was a week ago, I still do not have my advance in my Credit Karma spend account. I talked to Credit Karma and they say that the Federal Acceptance has not come through from TurboTax. Anyone know how to resolve this? Any help would be appreciated.
