They probably will ask for your passport, but if it's expired and you haven't traveled since it's expired it won't be a problem. It is not a requirement for citizenship applicants (or green card holders in general) to have a valid passport.I know people posted above said that it is not a requirement to show an unexpired passport, I assume they would ask me.
So the only reason you should need to renew the Turkish passport is if you need to travel overseas before obtaining your US passport, or if you need to visit Turkey after obtaining your US passport.
