Turkish dizi writing credits question

I was hoping someone with some industry experience or familiarly in Turkish tv production could help me with few questions I have.

Where do you find the complete writing credits, both for a series overall, and for specific episodes?

I'm going to compare Hudutsuz Sevda and Yeralti, since that is what I'm curious about anyway. I see a lot of people crediting them as the exact same set of writers, and and I can't find that specific info listed anywhere in either the episodes opening/ending credits, on IMDB, or on Dizilah.

There is one writer who works on both projects (Berna Aruz) but 3 are listed for Hudutsuz Sevda, and I can only find that one plus another name listed anywhere for Yeralti.

Quick note: I'm specifically interested in the writers. I understand there's a huge overlap in cast, directors, music and producers - which at least in American tv could either be a vanity credit or actually someone with some sway on story direction.

Both series opening credits do have a section for Senaryo (translated from google into Scenario - which could be either overall concept idea or could be writer - I think)

Hudutsuz Sevda***:***
Bahadır Özdener
Berna Aruz
Haydar Sisman

Yeralti:
Berna Aruz

There's also a section called Kurgu (translates to Fiction, though just from looking it up this might also be editor - seems like what that person primarily does according to google)

Kurgu for both HS and Yeralti: Serdan Cakular

Both Yeralti and Hudutsuz Sevda's ending credits also list another Kurgu: Ali Yigit Senturk

Hudutsuz Sevda's ending credits also have a different credit for Senaryo - Treatman (Scenario Treatment) as Masa Grubu

Dilzah lists Bahadır Özdener as a screenwriter for Hudutsuz Sevda, and only lists cast for Yeralti.

IMDB is clearly outdated and incomplete here, since there is a mismatch between the total writing credits and total number of episodes already released for both, but this what it says:

Hudutsuz Sevda (63 episodes)

Berna Aruz (57 episodes)
Bahadir Özdener (57 episodes)
Haydar Sisman 55 episodes

Yeralti (12 episodes aired)

Berna Aruz written by (7 episodes)
Raci Sasmaz story (7 episodes)

Does anyone know if there is a Turkish source with more accurate info? And please do tell me if any of the translations are wrong or faulty, I'm depending on google translate here.

I'd really love to know about episode specific writers if that is available anywhere. I'd heard on twitter there was a writer for the first 15 episodes of Hudutsuz Sevda that left, but I currently don't have any more info on that. Doesn't look like it's reflected in episode credits at least. So if you have any details on that it would be much appreciationed.

It's been really hard to parse through, since I'm mostly familiar with American tv works, and I'm relaying on translated info, or other fans - who often talk about the writers/producers/networks as if they are a monolith instead of a team made up of individuals. And that's to say nothing of the fans credit the actors/actress as responsible for the writing anyway.
