I am confused about putting youtube channel 
I am a small youtuber so my yotube channel does not shows up while searching so I have to write my youtube channel or the link to my channel

Are you asking how to link your YouTube channel in the social links?
The link to your channel itself will work fine.

the link is wrong.
also this thread is 260~ days old

You appear to be putting it in wrong. Your channel URL isn't the "name" of your channel. At least not for you.
