Where do you put these tab? Directly in the pool?

No You need a 3” chlorine puck dispenser, which gets tapped into your pool plumbing. The input line taps into (from) the output of your pump and the out put of the chlorinate gets tapped into a (non heater loop) return (jet) line. So water flows from the output of your pump, into the chlorinator, out the bottom of chlorinator, into your pool via a return line ( jet in the side of your pool.

what is the width of the tablets? I need ones no wider than 1 inch.

This is an old question, but Dan answered wrong. The tablets are 3” wide and 1” thick. Maybe a hair over 1” thick. To be more precise: the diameter of the tablets is 3”. The radius of the tablets is 1.5”. The thickness is still about 1”

where are the 3" tablets made?

It does not say on the bucket where they were made. It only says “distributed by” Doheney’s.
