Why wasn’t my advance approved even though I was approved

I had this same problem???

The initial approval is just a pre-qualification. If you don't qualify, you'll receive an email confirming you won’t receive a Refund Advance. It will include information about why you were not eligible for a Refund Advance. Your federal refund (minus any other agreed upon fees) will be loaded onto a Turbo Visa Debit Card.
