I downloaded TV shows to my iTunes, deleted them, and they still show up?

Okay so a while ago, I downloaded TV shows to my iTunes on my computer. When I was finished, I deleted them all. Every time I plug in my iPhone, after it syncs, the episodes begin to download again on my computer. I delete them again. Next time I plug in, same thing.

Which made me think that they were stored on my iphone. Can't find them anywhere. No where on itunes anymore. But they still keep showing up! How can I just delete them for good?

Delete them off your phone and computer
