Hi,
We mean that the asterisks can be any value. In reviewing the issue we can see all those kinds of /?p=*** pages like: https://cfooncall.com.au/?p=sjdas or https://cfooncall.com.au/?p=sadakn all go to the homepage https://cfooncall.com.au/ .
While we are not seeing a canonical tag in the source code but we aren’t seeing those URLs appear in Google. It seems likely is just crawling the URLs and telling you it found them. It does not appear Google is actually indexing them and making them appear in Google.
We have seen this kind of issue before and usually what happens is that some searchbox on the site is not created correctly so Google gets into the searchbox and starts crawling URLs and reporting them.
To resolve this issue we suggest the following:
1. Contact your theme developer and ask them to verify that the searchbox has been created in a way that prevents search engines from crawling URLs.
2. Consider creating a robots.txt rule which will tell Google to not crawl those URLs. This guide explains how to edit the robots.txt: https://yoast.com/help/how-to-edit-robots-txt-through-yoast-seo/
You can use this guide to create a disallow rule: https://searchengineland.com/a-deeper-look-at-robotstxt-17573
