It does appear that TK V fares only earn 25% EQM/RDM. That's quite a hit. If I were you, I would definitely credit this flight to another FFP that earns at least 70% EQM/RDM since OZ has a 2-year period for requalification.
Your other option would be to "buy up" to the fare that earns 100% EQM/RDM on OZ.

Thank you for the answer.
I will ask what the buy up fare is but it seems most likely I will just credit it to UA since it earns 100%.
