Let me provide you with the steps to replace your banking information in QuickBooks Online (QBO).
Here's a step-by-step guide on how:
On the left navigation panel, click Transactions.
Select the account on the Bank transactions tab for which you want to change the information.
Choose between Edit sign in info or Edit account info.
You'll be redirected to the login page when you click the Edit sign in info. However, the option to Edit account info will allow you to change its name, account type, and detail type.
