90% of disk space is occupied

[Hannzo96]

Hello, I dedicated 20 GB for Kali partition but there's only 1 GB free space in my kali partition although I didn't download anything and there aren't big files on my kali partition, I tried sudo apt-get autoremove to free some space but still i don't know what's taking most of the space
when I run df -h , the /dev/nvme0n1p6 is the most used directory, if anyone can help me fix this I'll be grateful

Depending on which 'flavour' of Kali you have installed 20 GB can be easily used up.. needs 40 GB really..
