Hello,
Most often a blog's feed is the blog url (web address) with /feed tapped on at the end.
So for example, my website is
www.yourtrueharmony.com and it is Wordpress blog. The RSS feed for my blog:
http://yourtrueharmony.com/feed/
So, the same is most probably true for you. The feed would be your blogger url, plus /feed at the end. You can test it out by simply entering your blog url plus /feed into your web browser and see if you get the actual feed displayed on your screen.
Also, here is a link from Google with some additional information on RSS feeds for Blogger blogs specifically.

Hope that helps! If you still have any questions at all, ask away.
