@Hal_Al is right @ABALLIETT.
I thought I read that @ABALLIETT was "broke" or something so that $30k on the 1099-K would be long term gain or loss BUT EVEN IF @ABALLIETT used a $0 basis @ABALLIETT it's hard to see where any tax would be due on the gain.....unless there's other income added in there.
