Perhaps it will help if you draw a normal box first, map corners, rotate one of the planes while still tracking the corners (see green) and then reconnect the corners into a twisted box.
Thank you for your feedback. I'm starting to get the hang of it by tracking the corners that change instead of getting overwhelmed by all of them. I really appreciate it
Do you know any exercises that can help with improving my understanding of the twisted boxes technique, particularly for mapping the corners of each plane?

Aside from what I already showed you I am afraid not.

Thank you for the feedback. I'll move on to the other techniques and keep revisiting twisted boxes over time. I know it will take a while, but I think that's better than getting stuck for now.
