Can you help me locate credit card transactions that should have been proceeded and posted two days ago?

It's my pleasure to help you, darnell. Let's go to the Bank transactions page to view credit card transactions and void a check by opening the transaction itself. The steps below will guide you through completing these tasks.

Here's how to find them:
 

1. Navigate to the Transactions menu and choose the Bank Transactions tab.
2. You'll find them in the For Review section. If you can't see them, click the drop-down arrow next to All dates, select Custom, and set the relevant dates. 
3. Then, click Apply.

If you can't see them, you can perform a manual update to refresh the connection. 
 

1. Go to Transactions and select Bank Transactions.
2. Make sure to select or highlight the Credit card.
3. Select Update and follow the on-screen instructions to complete.

For your next question, you can void a check manually by following these steps.
 

1. To open a check, click on the + New button and then select Check.
2. Click on the Recent icon located in the upper left corner. Find the check you want to work with, and if you need to see more checks, click on View More to access a list of checks.
3. After selecting the check, choose More and then Void. When prompted with Are you sure you want to void this?, select Yes.
