If you are consistently missing just to the right, your putting stroke is good. My brother is a golf pro in NY so I grew up leaning about all this so it could really be a bunch of things. Check your ball position because slightly back will push everything right, it should be consistent. Also, check your lead elbow, if it flares out, the putterhead won't release and you may push. Bring the elbows slightly more into the body without them feeling restricted. Most importantly, make sure your shoulders are square to the line. If they're open you'll pull your putts. If they're closed you push your putts out to the right. Most of the time a pushed putt also happens because you have moved your eyes off the ball prior to putter impact. Try watching the putter hit the ball, look at the ground where the ball was at & listen for the sound of the ball falling in the cup. A lot inconsistent putts come from this very little action that you do with the slight movement of the head and even moving your eyes. If you can control this, your putt (either it be push or pull) will be a LOT more consistent and predictable. By just working on this one thing, you will definitely save a lot of strokes. I found out that when I push the ball its usually because my right hand is dominating and when I pull it's my left hand that dominates the putt swing. Let the shoulders do the work and no wrist action.
