Where to enter the name of the channel when creating it on YouTube?

Question

YouTube

It's a funny situation... Today I decided to create a channel on Youtube, I've seen enough of all the manuals, but it seems that a lot has changed. Although you crack, but did not find a place where you can enter the name of the channel, everywhere there are only links and a description. Tell me plz.

Answer 1

https://www.youtube.com/advanced_settings -> Change title

Answer 2

Thank you. But as I answered Vlad, I was embarrassed that there is a first and last name and when you click change the name, a window appears with a separate change in the name, separately the last name, and below the pseudonym ... Actually, that's why the question arose. I am attaching a picture.
