Can’t find RSS Feed/feed not working

I’m trying to provide my RSS feed to someone who wants to subscribe via Feedly.

Wordpress support article (https://www.ads-software.com/support/article/wordpress-feeds/#finding-your-feed-url) says any of these should work:
https://example.com/?feed=rss
https://example.com/?feed=rss2
https://example.com/?feed=rdf
https://example.com/?feed=atom

But when I plug in my site address and use any of these, the address doesn’t give me the feed info – it just resolves back to my homepage. I also tried validating them here https://validator.w3.org/feed/ and it returns “It looks like this is a web page, not a feed. I looked for a feed associated with this page, but couldn’t find one. Please enter the address of your feed to validate.”

I don’t know what I’m doing wrong or how to fix this.

Thanks!
