I am using the latest (as of 10 Oct 2023) Quicken Classic Starter Edition on Windows 10.
For a Tax Schedule report there is no "Tag" column and Customize > Show Columns does not offer Tag as an option (see screen shot). I have tags defined and they are not marked as "Hide". At least one entry for the report period has a non-blank tag.
This worked for me a year ago. Has something changed? Am I missing something?
