@LillyR there is no longer a My Forms page but instead, above My groups you should have the following home screen showing, recent, Pinned and Shared with me. This lists your forms. Don't you have that? At the bottom right of that list, just above My groups is a link to All My Forms which you should also have and which gives you access to the copy & move form options.
