Search Bars and sidebar

I would also like to know! The search bar in the blog posts section is not even listed in the widgets, yet, there it is, big as day. I have changed every setting I can think of, but it is still there. Help!!

You can see it here on the blog post

I figured out the search bar issue. Finally.
Go to Appearance, then customize
Customize layout
Default layout
(My side column is on the right and the search bar was showing up underneath the picture on every page but the home page..)
I simply unchecked Top First Sidebar which removed the search bar from underneath the picture ??
Hope this helps! I actually just pressed every button til I found the right one……:)
