How can I find the current location of my plot?

I purchased Plot No. 38 in Survey No. 124/48 of R R District, Serilingampally Mandal, Gopannapalli Village, Hyderabad, measuring 300 sq. yards, in 1990, and it was registered in my name via Registered Sale Deed No. 9439/1990 dated 25th July 1990. The plot has remained in my name in the Telangana Registration and Stamp Department till today. However, I recently learned that in November 2006, the land was acquired by the then Government of Andhra Pradesh. I approached Prajavani in Hyderabad on 29th December 2023, and in response to my grievance, I was informed on 19th July 2024 that the application had been examined by the Additional Mandal Girdawar, who submitted a report stating that the matter is a private dispute and that I should approach the civil court. Kindly advise: 1. Who should be named as respondents in the case, as I am unaware of the current holder of the plot? 2. How can I determine the correct location of the plot?
