If you've deleted everything with terragrunt or terraform and you want to save disk space on terraform providers and modules, you can try the following. YOU MAY LOSE STUFF THAT'S PRECIOUS TO YOU. IF YOU'RE NOT CERTAIN THEN DON'T DO THIS.

# remove the providers and modules you've downloaded
find . -type d -name ".terraform" -exec rm -rf "{}" \;
# remove the configuration lock file unless you don't want to 
find . -type f -name ".terraform.lock.hcl" -delete
# remove the state file because there's nothing to track the state of ... you hope
find . -type f -name "terraform.tfstate*" -delete
