Jcomments at front pages

Thanks for your excellent design, I am new to Joomla just need some help on the Jcomments block (at the bottom of page) at the front page. I want to replace the front page Jcomments block to a K2 comment block as I want to standardize the whole site but I can't seem to find the module to remove/disable the Jcomments block. Please do advice on this thanks.

The K2 comments module is called "Your Opinion." The "JComments" module is called by it's own name plus the word "Latest." You can disable one and move the other to whatever position you wish.
