My DD is currently doing drills pitching on a 1X6 to stay on the powerline. Seems to help.
Just doing K or T drills? Or full out motion?
My DD does the same thing. I put cones just to the right of the power line where here plant foot lands. If she kicks the cones, she gets feedback that she's stepping over the line.

Videos are more helpful to get better advice.
If she is missing inside it has nothing to do with stepping across the power line. There are other issues at play. Really need a vid. If I had to guess I would look at the hips,
