Picture would help, but yes you can cut right where the new green branch starts. I would take look at the nodes buds and cut it above the node above the bud that you want the new branch grow.

Will send a photo. Thank you. Will cut there. No leaves yet, hoping they get better once outside again.

Next winter, try putting them in a cool area, low light (or cover) and don't water or feed them. I kept mine in my cool basement that way - along toward the end of March they would start to awaken from dormancy and start putting out leaves - that is when I would bring them into light and start to water. Now they are big so I keep them in the unheated garage, covered with an old quilt or blanket (still don't water them until they can be outside.)
