The Space Stone (Tesseract) and Time Stone (The Eye of Agamotto) are the two stones that are/were on Earth. Soul likely is too, imo.
edit: Speaking of the Tesseract, we could potentially get the Red Skull's return, as he was seemingly transported somewhere at the end of CA:TFA. Doubt it, but you never know.
Assuming you’ve heard of the T.H.A.N.O.S. initials theory, what are the possibilities that Heimdall is the bearer or the living embodiment of the Soul Gem?
FYI:
Tesseract (Space) from the CA: The First Avenger
H- ?????
Aether (Reality) from Thor: The Dark World
Necklace (Time) from Doctor Strange
Orb (Power) from GotG
Scepter (Mind) from Avengers
Like I said, it's possible the soul gem doesn't even exist in this universe. They went that route for the cartoon based on the movies.
Wait, there was that one scene where Thor goes to a magic well and see's the infinity stones. How many does he see?

Though if Heimdall does indeed have an Infinity Stone (Soul) inside him or it is a part of him, he could have likely given Hela a run for her money all by himself.
Personally, Wakanda is my first choice for the soyl stone's location, considering the Heart herb and it's ability to connect people with the soul's of their ancestors, aside from super-powering humans. My second would be the Soul Gem is with/powering/powered Adam Warlock. We've had multiple hints he's going to show up at some point.
Keeping in line with the shitty and very overrated comic book story, where Thanos already had supreme power.
