I ran an itemized payees report filtering on a single specific payee, which produced the desired result.
Then I attempted to print via the Adobe PDF printer, and Quicken became unresponsive. I left it alone for about 10 minutes but it never returned. Eventually I terminated the Quicken process and restarted.
Now, specifying the same single payee filter no longer works. The report includes several other payees unrelated to the one I specify in the filter. If I return to the customization menu I see many other payees checked. If I then click "Clear All" and re-select the single payee I want, the report still includes other payees, totally unrelated.
I have run the "File/Validate and Repair" function and it detects no problems.
I have closed and restarted Quicken several times, and also rebooted the system.

Workaround:
I found a workaround, which is to use the filter dialog and then ALSO specify the payee name in the "Matching" section, as in:
