I ereased current MacOS system and tried to setup new version from scratch. But Macbook can't show internal SSD in diskutil anymore. I can't access my SSD in Macbook. Whan I tried until now and results:
1) I was have bootcamp in it and I tried to access to Windows on Macbook, I accessed, but Macbook's own firmware couldn't see it anyway.
2) I have tried SSD and tested everything on it (GTP opening, format settings etc.) everything works very fine for SSD.
3) I have tried install a MacOS to my flash disk from internet recover system, it worked.
4) I have booted 2 different USB sticks (3.0, 2.0) they both never seen as bootable but I can see them in disk utils.
5) I tried reset thing on Macbook (CMD + Option + R + P) didn't work for me.
6) I tried 4 different DMG files with 4 different versions of MacOS (by using TransMac) and I tried to boot all of them on Mac but never worked.
7) Everything was fine until I pressed to "Erase" button on Disk Utility in CMD + R at startup. I just wanted to reset everything and install a fresh setup but that locked my whole day.
I have tried everything what I can find on the internet but it never see any internal storage anyway.
(I mean OS never sees it but bootcamp was still working when even OS can't see it. Until I reset SSD on my Windows PC, I can access to Bootcamp Windows from Macbook Pro after Erasing MacOS Catalina.)
Thank you everyone…

I found the solution. I have an NVME SSD because of that Yosemite or El Capitan can't see it. I just created an High Sierra boot USB and that solved my problem.
