In my pretty standard dnsmasq setup, upstream dns is
in /var/run/dnsmasq/resolv.conf. From the manpage:
-----
In order to configure dnsmasq to act as cache for the host on which it
is running, put "nameserver 127.0.0.1" in /etc/resolv.conf to
force local processes to send queries to dnsmasq. Then either specify
the upstream servers directly to dnsmasq using --server options or put
their addresses real in another file, say /etc/resolv.dnsmasq and
run dnsmasq with the -r /etc/resolv.dnsmasq option. This second
technique allows for dynamic update of the server addresses by PPP or
DHCP.

So, 'ps ax | grep dnsmasq' ought to tell you where upstream is (that's
how I found mine).
