What bank is my Quickbooks card attached to?

 I've just got the details you need, John.

You’ve mentioned about QuickBooks card. Are you referring to the QuickBooks Cash account?

If so, QuickBooks Cash is handled by the Green Dot bank. This is the external partner institution by QuickBooks that helps handle your money. For more info, please check this reference: QuickBooks Cash.
