In spin-off games

Pokémon Mystery Dungeon series

TMs in the Mystery Dungeon series are named only by the move they teach. For example, Attract is the item that teaches the move Attract. Most TMs, however, correspond to a TM in the core series' contemporaneous games.

TMs in Red Rescue Team and Blue Rescue Team and in Explorers of Time, Darkness, and Sky, TMs can only be used once before becoming Used TMs. In Gates to Infinity, TMs can be used any number of times. In Pokémon Super Mystery Dungeon, some TMs can only be used once while rainbow-colored TMs can be used any number of times.

In the manga

Pokémon Adventures

Gold, Silver & Crystal chapter

In Elekid Incorporated, Silver mentioned that he had used TM21 to teach his Totodile Frustration in order to capitalize on the fact that he had only just stolen the Pokémon and it hadn't come to like him yet.

Trivia
