can I make my lists private? when I go to edit them all I get is name, description, tags

I don't think you can do it to individual lists... but I think you can do it to your lists as a whole.

wait no you can only hide it from timeline, I read it wrong...

I went to the setting and clicked hide on " add manga to list" can you check if my list content is visible on my account?

yes... Σ( ￣□￣||) I don't think it's possible to make it go away...
