Roamio arriving wednesday and I have Time Warner, do I need a tuning adapter?

When I called and ordered the CableCard from Time Warner I knew nothing about them so I didn't know to ask for a tuning adapter and they didn't say anything about it. Only reason I know about the tuning adapter is a I Googled Roamio and TWC and what I read mentioned the tuning adapter. Do I need to call back and tell them to make sure they include a tuning adapter? I live in NE Ohio (Dover, OH to be specific).
