what is the proper way to paper tune ( distance wises and how many different distances you should do it at)

I start at about 6 to 10 feet & then move to 20 yards. If you just do it at 20 yards you may miss or the arrow may correct by the time it hits the paper and vice versa if done at just a close distance.

I use 3, 8, and 15 feet. These three distances give me excellent results once I hit the range, and besides that' s about all the room I have in my " shop" area.
