You can't change anything in iTunes itself: you have to change it in the feed. Whatever program or service you use should have a place where you entered the catgegory in the first place: change it there and re-publish the feed. it will take the Store a couple of days or so to catch up - it might not catch up until you publish a new episode.

Tha'ts the only method. The Store may take a few days to pick up changes. It's not really possible to comment further unless you would like to publish the URLs of both your feed and the Store page - this latter can be found by control-clicking on the podcast image (or where it should be) - and choosing 'Copy link'. Please include the http:// in both cases to make the links clickable.
