RSS feed missing

Hi, I’m a newbie so be gentle please :).

I just set up my first proper wordpress site and I am trying to find my rss feed url so that i can submit to feed burner etc and add an RSS button to my blog. Everyone is telling me that it should be there by default but it is not. I have read forums which say to try various combinations like https://www.site.com/rss etc but none of these work. In other words I don’t think it has an rss. can someone please tell me, in the most simple terms possible, how to get rss working on my site with the rss button too?

thank you ??
