“All Pokémon Powers stop working until the end of your opponent’s next turn.”

Which is also at the end of Current turn + 1 in TCGONE. The card was played Turn 3, was in effect for turn 3 and turn 4, and at the end of turn 4 (the next turn after it was played) it stopped.

Technically it ended at the start of turn 5 instead of at the end of turn 4, I assume because between turns is still supposed to be under the effect so beginning of turn 5 is shorthand for covering that essentially.
