Is there a section you can explain withdrawals on transcript on AMCAS?

I got to a public uni and with some of the federal changes, I don't have to take a class anymore, but would need to withdraw. It's a particularly difficult class, but it takes a lot of time, and I would really like some extra time to focus on ECs or build other parts of my app with the extra time. Only downside is it is too late to drop without the W. I wanted to ask my premed adivsors about this, but they take a ridiculously long time to answer. I just want to make sure there's someplace I can explain this W on my transcript. Note this would be the only one I have.
