Welcome to Waze editing in Tennessee! First, to answer your question, the change you made today should go live in the app "LiveMap" in the next 48 hours, though on some occasions it can take closer to a week.
I've looked at the edit you made and we need to make one change to the work you did. You added Murfreesboro as the city name, which at face value would make sense because your mail says Murfreesoboro. However, you live outside the official city limits of Murfreesboro, so we need the city name to stay "No City" as set by the check box. Then we need to "Add alternate name" that says the street name again and there states Murfreesboro as the city name. So it should have these names:
Primary: Farmbrook Ct, No City
Alternate: Farmbrook Ct, Murfreesboro
This avoids what we call "City Smudge," where the city name that you sometimes see floating on the Waze app screen might appear outside of the city limits. https://wazeopedia.waze.com/wiki/USA/Smudged_city
