TK website still broken with regards to partner issued award ticket PNRs. I have had the same issue with my TK flight booked with UA miles. Unlike LM, UA issues separate PNRs for each airline involved in the booking. I tried the TK PNR many times without luck. I finally decided to try their mobile app (Android) and it worked like a charm. You do need to have the ticket numbers though.
