Hello there, Peter.

Currently, we're unable to customize customer statements in QuickBooks Online (QBO) to display only the list of received payments. However, you can create and download a Transaction Statement, so you can manually edit it outside the program. Here's how:

1. Go to Sales and select Customers.
2. Locate the customer's name and click the Action dropdown. Then, select Create statement.
3. In the Statement Type dropdown, click Transaction Statement.
4. Enter other necessary information.
5. Select Print or Preview and click the download icon.

Alternatively, you can run the Transaction List by Customer report and customize it to show only the payments. To do that:

1. Go to Reports and search for Transaction List by Customer.
2. Click Customize.
3. Go to the Filter section. On the Transaction Type dropdown, select Payment.
4. Enter other necessary information, and click Run Report.
