New MacBook Air Storage

Hello everyone,

I just received my MacBook Air today and I used migration assistant to transfer everything from my my 2016 MacBook. My older macbook had the same storage space of 500gb and to this day it still has 250gb of space left. After having to do do migration assistant 3 times because the new air kept wanting to freeze, it finally migrated everything. As I was checking storage, I noticed that I only have 113gb of space left. How is that possible? I see that "other" is taking up like 280gb. I also noticed there are duplicates of things in one of the folders, which I'm assuming happened after the migration attempts. How can I delete these duplicates and where can I find this hidden stuff that is taking up storage?

Thank you in advance!
