You should definitely perform 20 rak‘ats of Tarāwīh. For more detailed information, kindly visit the following link:
Taraweeh - 20 rakat or 8 rakat??
If there are no Masjids in your locality performing 20 rak‘ats, you can join them for the 8 rak‘ats and perform the remaining 12 individually at home.
And Allah knows best
