Sidebar is too far to left

While editing my stylesheet, I did something to mess up my sidebar, and now I can’t figure out how to fix it.

My blog is at https://www.amptoons.com/blog .

Thanks very much for any help. I’ve pasted what I think is the relevant part of the stylesheet at the bottom of this post.
