Is this true?
"I confirmed it. İzmir (F-516) and İçel (F-518) were sold to Indonesia. İzmit (F-517) will be delivered to the Turkish Naval Forces."
In my opinion, that's the case. Indonesia wouldn't order a ship if it hadn't been produced yet and would collaborate with a local shipyard if it were to be produced.
otherwise it will take quite a long time like FMP case to declare that Indonesia has purchased the ship
We call it "begal"

, Like PPA case
The photo shows hull numbers 516 and 517. Why would they display two numbers if they weren't for Indonesia? The first hull number, 515, would suffice.
