You should assume the location given on the citation is the one when the offense is alleged to have occurred. Your TBD should state you did not run any stop signs, and that the particular intersection noted on the citation does not even have a stop sign. You should prevail.
If you sent your discovery request to the police agency for which the citing officer works, they should respond. They are in fact required by law to respond in infractions. If they don't, it's actually a good sign. The officer may have realized he made an error - whatever it was - and will pursue it no further. If they don't respond AND you are convicted in TBD, call the court and ask for the statement submitted by the officer. That will tell you all you need to know for trial de novo.
Things are looking good.
