Thank you for your quick reply and things for me to do.

The version of QuickBooks I listed is the latest ("QuickBooks 20.0.13.1096 R14.2 is currently the newest version available.").

I ran Verify Data: "No problems have been detected in your QuickBooks data."

I ran Rebuild Data: "Reload and rebuild has completed."

"you can also check this article on how to reconcile your accounts to match your bank and credit card statements: Reconcile accounts in QuickBooks for Mac."

I'm not asking how to do that; as I wrote, the transaction (credit card charge) I am trying to duplicate was entered manually.

When you attempt to do what I am after in the QuickBooks product I am using, does it work for you?
