in what package is TCM channel included?

I can't find it anywhere on the xfinity website. all i want ot do is get the TCM channel. I seem to recall it was moved into some kind of "package" with other channels and i can't find out which one it is in and what the other channels are. why do make it so difficult? I have tried "chat' and all I get is automated answers that do everything EXCEPT answer the question!
