It's nice to see you here in the Community, @heidisskincarest.
Let me show you how to add another bank account in QuickBooks Online (QBO) by following the steps below:
- On the left pane, navigate to the Accounting tab and select the Chart of Accounts.
- At the top right, click New.
- Select an Account Type, Detail Type, and Beginning Balance.
- Enter the name differently by adding another character to set it apart from the first bank account.
- Select Save and close once finished.
Doing this will add a bank account to your Chart of Accounts for holding manually created transactions without a live connection.
For additional information, I've attached articles you can use to connect a bank account to QBO, manage the downloaded transactions, and set up sub-accounts:
