on my 5th profile.... I hadn't played them on that profile yet

In order to obtain Mew and Jirachi, you’ll need save data on your Nintendo Switch from Pokémon Sword and Shield for Jirachi and Pokémon: Let’s Go for Mew.

You just need save data on your Switch, not the specifc account you're playing with.
Hope this helps!
