I applied for the advance which will go on the credit karma debit card. Will the rest of my refund go on that same card?

Yes it will all go on that Credit Karma card.  That is what you agreed to when you accepted the advance offer.

Ok thats what I thought, thank you. How do I know I was approved for the advance? Is it like a credit card and they will email me about it later?

They are supposed to email you and they will mail you the card.
