try this:
k3s server --kube-apiserver-arg --service-node-port-range=20618-20828

Just a little update here for anyone else coming across this issue:

The correct version of the specifying the argument is (as of k3s version v1.19.5+k3s2 (746cf40)):

k3s server --kube-apiserver-arg service-node-port-range=1000-32767

If you installed k3s as a systemd service (the default via get.k3s.io), you can make this change permanent by adding the command line argument to ExecStart in /etc/systemd/system/k3s.service, e.g.:

# ...
ExecStart=/usr/local/bin/k3s \
    server \
    --kube-apiserver-arg service-node-port-range=1000-32767

Then systemctl daemon-reload and systemctl restart k3s.
