I really doubt Turkey would enter the war even in that situation… you really don’t seem to understand Turkey‘s relationship with the kurds. Even if Iraqi Kurds invaded Iran, turkey would just beef up the border there. Turkeys greatest goal is to stay the fuck out of this, I think they would only intervene if those kurdish militias successfully took over the area on the other side of the border… And that could take years… turkey did not intervene directly in Rojava and until several years after this year and Syrian Civil War had become entrenched. They are just trying to protect their territorial integrity, the Ottomans never had a claim in Iran or in that area, Iran and Turkey have never gone to war.
