"I don't know it top off my head" means that you cannot remember a specific bit of information exactly right then. "I do know about it" means that you are at least somewhat familiar with a topic in a general way. The two ideas do not go together. If you remove "about", they do: "I don't know it top off my head, but I do know it." I added the obligatory comma.
