Hi there, John. It's my pleasure to help you transfer the $500 from your QuickBooks Checking account to another account.
Usually, before closing your QuickBooks Checking account, it needs to have a $0 balance. You can either spend your remaining amount or transfer it to your external bank account. Since you have a $500 balance on your closed Checking account, you need to contact Green Dot for further assistance. From there, they can pull up your account securely and initiate the transfer.
You can review the contact details on the back of your debit card.
