Green Dot Bank is also one of the intermediary banks involved if you chose to pay your TurboTax fees out of your Federal refund.
We don't know the context of your question and where you are seeing a reference to Green Dot Bank.
I see you have another question at the link below which references Green Dot Bank, but you didn't explain much there either. Maybe you should explain your situation in full, and we can tell you how to check on your funds.
