I AM POSTING BANK INTEREST AND i NEED TO ID THE SOURCE AS A BANK AND NOT A CUSTOER OR VENDOR- HOW DO I DO THAT

Welcome to QuickBooks Community space, @resol.

I'll share with you some steps in recording bank interest in QuickBooks Online (QBO).

You can record bank interest in QBO by creating an account. Let me guide you through the steps.

Here's how to create an account: 

1. Go to the Accounting tab on the left side. 
2. Select Chart of Accounts, then hit New. 
3. Under the Account Type column, select Other Income. 
4. In the Detailed Type drop-down, choose Interest Earned. 
5. Type a specific name in the box. 
6. Tap Save and close. 

After that, let's go to the Plus icon, then choose Bank Deposit to post the amount. 

1. On the Deposit page, choose the account you've created. 
2. Enter the amount. 
3. Hit Save and close.

I'm also adding this article for your guidance in reconciling an account in QBO: Reconcile an account in QuickBooks Online.
