If you believe SeatMaps.com, it's the configuration you noted above:
https://seatmaps.com/airlines/tk-turkish-airlines/airbus-a330-200/#a8e5a72192378802318bf51063153729
The reason why there are bassinets in two rows is because rows 4 and 5 are behind the door/bulkhead (Turkish won't show that on their seatmaps).
From this thread:

"The only A332 with 30 business class seats in the TK fleet is the oddball TK-LOM, which was originally operated by Avianca. Planespotters lists it incorrectly as having a configuration 24J 222Y but it has actually stayed in its original configuration 30J 222Y. So that is the aircraft depicted in this seatmap"
But...if there is really only one 332 configured like that in the fleet, I think there is a very low probability that you will actually be on that specific plane in October.
