"Smash" its just a parody of the main work, with no relationship with its plot... TUM, on the other hand, takes place in the same timeline. Everything seems to indicate that it takes place between the Festival arc and the Joint Training arc, among which there are months we hardly know anything about the students and their activities.

The manga has just started and it is normal that it has no references in the main work, the same happened with Vigilantes (no reference until several months later with the Trigger drug) Of course I know it has not been confirmed whether it is canonical or not but its fully supervised by Horikoshi himself.
