How do i change my bank account details on my account

I've got the steps you'll need on how to change it, jules-thefoxagen.

You can follow the steps below:

1. Go to the Gear icon and select Accounts and settings.
2. Select the Payments tab.
3. Modify the deposit information.

You can refer to this article for more details: Common questions about payments deposits in QuickBooks Online.

Also, I am adding an article about how to find missing payments in QBO: Find missing payments you want to deposit in the Bank Deposit window.
