It's normal that the official processing date exceeds your priority date, and you're only one of the many people who are in the same boat. Sometimes, no news is good news, just wait patiently, it will come to your turn eventually. If you do worry about it, call the national immigration service center (NISC) directly, they can issue an inquiry for you, but you probably won't hear back from TSC in a month or so. I'm not sure if you called TSC or the NSC, it would be odd if NISC requires a lawyer's call.
