Finished it, but can’t justify the answer for 20 down…
Eye’s impounded by government agency - flipping harsh! (7)
ASCETIC
I believe “harsh” is the definition, and I assume it’s something related to “eye” inside a reversal of a government agency.
Can’t see it though!
CSA used to be a government agency, but I don’t think it’s called that anymore more.
Can anyone justify this answer?
