turn the nut boat but wait....uh oh.

hi everyone
this hand occurred in a loose 20-40. pretty cut and dry. a player who hasn't gotten too far out of line post flop reraises a KQQ board against my AA. it gets capped and we're heads up.

on the turn the A hits giving me the nut boat. bet, raise and he calls. but then the Q hits on the river. now i know he has the Q when he reraises my river raise. shoot, when he bets into me i know he has the quads. but i 4 bet all-in the river anyway. how bad is the four bet here? can you ever put your opponent on quads?
