Put your hand in the crease between the seat bottom and seat back and feel around. You should feel the anchors in there- they are pretty deep in some seats. There should be two U shaped hooks for each outboard seat. Toyota does not allow "borrowing" the two inner anchors to install a seat in the middle. If you need a seat in the middle you must use the seat belt.

I'm sure they are there - you just have to feel for them alongside the places the seat belts come out between the seat and seat back.
