Wanda’s Connection to Pietro and Vision
Wanda knew because one she was probably told by Clint or the other Avengers or saw him on the “lifeboats that SHIELD sent to Sokoiva.” Before then I think with her telepathic abilities she was sort of telepathically connected to Pietro and so felt it when that link went quiet because he died.

This makes Wanda 28 years old when she was snapped out of existence in Avengers: Infinity War and while five years have passed, she maintained that age when she was resurrected in Avengers: Endgame and several weeks later in WandaVision.
