Western Turkic Khaganate = Onoq budun
First Turkic Khaganate = Idi Oqsız Kök Türük
Göktürks = Türük Bodun
Turk is a later term same as the term Byzantine
1. Islamized Oghuz named Turkmen
2. Turk is mispelling of Turuk, however Turks are not Turuk but that's how Arabs called the islamized Oghuz, and Turuk who islamized later.
...
So the so called "Turkic" populations very often they are not connected or related to each other.
☑️Turks from Turkey (modern Turks) are a mixture of Janissaries mixed with Turkish women, Turks and Janissaries mixed with slaves, and all that mixed. And of course native populations that Turkified.
☑️Oghuz in Mongol Altai Mountains or around, were a dominion of Xiongnu.
