Hello there, patsaustin.
I appreciate the steps you've performed and the details you shared. Let me provide clarification on how the Payment Method works in QuickBooks Online and ensure you can run a report with complete data.
Although the payment method can be selected every time you create an invoice, it is only used as a selection for your customers when they pay invoices. The chosen method in the entry will not appear on the report.
Furthermore, the information displayed in the Payment method column is the preferred method of the received payment. With this, you have to make sure that the appropriate details is configured on the said entry.
In case you need steps on how you can memorize a report that allows you to save it with its current customization preferences, you can read this article: Memorize reports in QuickBooks Online.
