2006 Nissan Altima Loose Hose - Anyone know where this should be connected?

Found this loose hose just now. 2 pics with same hose. Anyone know how I can find out where this should be connected?

Hose says TN 6102 (not sure if that even helps)

is this a transmission breather hose?

It’s the AC condensation drain hose.
