When my credit card payment is automatically matched, how do i verify detailed line items from credit card?

I'm here to help you view the detailed line items of the categorized transactions, @Moxie 21 Win.

When the transaction is matched, it will automatically move to the Categorized tab. Then follow the steps below.

1. From the Categorized tab, locate the transaction.
2. Under the ADDED OR MATCHED tab, click the link to open the transaction.
3. You can now see the detailed line items.
