MacBook Air, OS 10.15, 85GB file in "other", can find it to delete ... help

I have a 256GB 2020 MacBook Air, it's working fine.
However, there's a mystery of 85GB file in "other", can't find it to delete it.
I suspect it was a Parallels windows Partition I created on my 2015 iMac (It has 3TB Hybrid drive) and migrated over here when copying that user account, but I don't use parallels in years and can't check.
Very frustrating a huge file is hidden ...
TIA, Mike R

If you use homebrew, install ncdu. That'll tell you everything.
