YT Bell icon will show you replies to your comments, but only those where someone directly clicked "reply" on your comment. YT comments are 1 deep and if someone replies to a reply to your comment you wont get notified.

also https://www.youtube.com/feed/history click Comments on the lower right.

But this wont show deleted comments. I had comments disappear, and later video creator tell me he saw it (got notification) before it was automagically deleted by Google, those comments vanished from YT history.
