Hi there, Halyna. You can go directly to the Payments tab on your QuickBooks Online (QBO) account to update your bank account for the QuickBooks payment account.
Please note that you must be using a web browser to make this change, as you cannot update the account from the mobile app or QuickBooks GoPayment.
To update your bank account, click on the Gear icon and select Account and settings. Next, navigate to the Payments tab. In the Deposits section, choose Change bank, and then click on Add new bank account. Finally, follow the prompts to complete the process.
For more details, you can also check this article: Change the deposit bank account for QuickBooks Payments.
Feel free to return to this thread if you have any follow-up questions.
