RSS feeds

I couldn’t find an answer, at least not a recent one, or one I understood. How do I find the URL for the RSS feed for my blog? I was told it was https://terryodell.com/terrysplace/feed/ but that isn’t working.

I’m trying to have the RSS feed on my blog’s sidebar.

And, on the same note, the feed to Networked Blogs doesn’t work either. I used the above feed, and it said it was fine, but it’s only showing the first few posts to my blog.

I’m totally stumped.
