Where is the 301 redirect table?

I need to change the URL’s of my criminal lawyer pages and immigration lawyer pages. So I edited the permalink on steventress.com/immigration-lawyer/ to steventress.com/immigration-lawyer-toronto/ and wordpress automatically set up 301 redirects for that page and all the child pages. Fine. But when I did the same for steventress.com/criminal-lawyer/ to steventress.com/criminal-lawyer-toronto/ it set up redirects for all the child pages but incorrectly redirects steventress.com/criminal-lawyer/ to the home page steventress.com.

WordPress has a table somewhere of the 301 redirects it sets up automatically, but I can’t find it. I think there is an orphan entry in there which redirects that page to the home page if it is not found, instead of the new permalink. Do you know where that table is so I can just edit that entry?
