I added my business credit card account to categorize expenses paid on CC. When I pay the full CC bill, how do record that expense which is going out of checking account?

I can help you record your credit card payment, @neeraj11_2. 

Here’s how: 

1. Select + New. 
2. Under Money Out (if you’re in Business view), or Other (if you’re in Accountant view). 
3. Select Pay down credit card. 
4. Then select the credit card you made the payment to. 
5. Enter the payment amount. 
6. Enter the date of payment. 
7. Select the bank account you paid for with the credit card. 
8. If you made a payment with a check, select I made a payment with a check. In the Check no. Field, enter the check number, or if you paid electronically, enter EFT number. 
9. Select Save and Close. 

In addition, I recommend you reconcile your accounts regularly to ensure your bank accounts are balanced and accurate. You can check this article: Reconcile an account in QuickBooks Online.
