Won't let me switch my instant deposit back to my quickbooks checking account. Everytime I click it then submit the 6 digit, next screen says oops something went wrong.

Hello there, tearance. Let me provide information regarding instant deposit and route you to our designated support. 

Before anything else, let me provide information regarding instant deposit. It's an additional service in QuickBooks Payments. Your account must be active and in good standing to be eligible. You'll need to set up your debit card or bank account where you want to get an instant deposit.

For more information, refer to this article: Get instant deposits in QuickBooks Online.

Meanwhile, I recommend contacting our payment support to check the error message you've encountered and if your bank account is eligible. This team is specially trained to handle payments-related inquiries and can provide guidance, information, and support.

If you have a QuickBooks debit card, you can contact our payment support team by dialing the contact number on the back of your debit card. Once connected, you can speak with a representative who will assist you in resolving your concern.
