How to link Facebook and Twitter accounts in YouTube?

Question

YouTube

There is one main YouTube account, but it had 2 violations, I had to leave it for 1 year, in order to get a good reputation, while that account was "sleeping", I had to create an additional one, through the same account from Google. Not long ago, the violations were removed, I decided to delete the old YouTube account, but there was also a problem, when entering the old channel in chrome, it gave the error "A cyclic redirect was detected on this page." But by some miracle, I went to the channel and I was required to create an additional channel so that I could use this one that I tried to go to. And this is where the whole story begins. When I try to link my Facebook and Twitter accounts, they are not linked on this channel, but I am thrown to a side channel and when I refresh the page, I always find that the link took place on the YouTube side channel,
