How can I edit the meta widget to remove rss, etc.?

In the footer of theme gridmarket (multisite), I added the meta widget for a proper loginout button, and what comes up once logged in. Along with it comes too many other functions.

I would like to remove rss feeds and worpress.org from the meta widget. I have searched widgets.php, meta.php... where does the meta widget code exist?

Or what is the correct code for these functions to add to a text widget?

Thanks.
