It's not there any more - you're looking for the 'Altera GPIO Lite'.

There is a lot - yes, a lot - to be said for capturing your design in rtl. I (also) suggest you look into this. There are plenty of self help tutorials online. You wouldn't be struggling with this IP issue if your tri-state buffer was inferred in your code. Quartus would simply implement the appropriate buffer from whatever FPGA family you're targeting.

Cheers,
