What is `intu-ec-client` listening on TCP port 8021?

I'm wondering how I can either kill it or change the port it listens on. Neither lsof -nP -i4TCP:8021 | grep LISTEN nor netstat -av | grep 8021 or launchctl list | awk 'NR>1 {print $3}' | xargs -I % sh -c 'launchctl list "%"' > launchctl.log give me the process ID so I can kill it or get more info.
