In 2011, TK didn't contract a lounge in AGP.
However, that is 8 years ago and the information may have changed.
Also, the Star Alliance Lounge Finder does not show any lounges for TK.
You might send a tweet to their Twitter team; giving lounge information is one of the rare things that they could to properly.
