I have too many youtube channels under one email. How do I get rid of the extra youtube channels?

So I have one name that I use and a bunch of extra names I either made by accident or don t want to use. What is the step by step process on how to trim the fat?

1. Click on the circle with your channel avatar on it
2. There is a drop down. Click on the channel you want to delete. Youtube will refresh the page and you are on that channel now.
3. Now click on the circle with your new channel avatar on it again and click on the gears icon next to "Creator Studio".
4.You are taken to the "Overview Page"
5. Under your name, there is a small link that says "Advanced". Click on that.
6. The last thing on the page says "Delete your channel".
