A pawn can be promoted to any piece if it makes it all the way across. 9/10 you'd choose a queen coz... well why wouldn't you? On occasion you'd choose a knight coz it may be just what you need to checkmate from an odd position... but other than that anyone who gets a pawn all the way over is going to pick a queen.
I have been playing chess my whole life and have never heard of this. You also can't move pawns backwards.
And they don't turn to queens, that's checkers.
