I believe Turkey owns those F-35s operating in the US, they're used for training. On that Wikipedia page you can see there's dozens of F-35s in the US owned by foreign air forces.
Can they just fly them out of the US at this point? No idea, but it's interesting to see what'll happen with that.
Just because Russia has S-400 advisors in Turkey doesn't mean they get to walk around wherever they want, including wherever the F-35's engines are serviced.
The concern was specifically that they'd have access to detailed radar data on the F-35, which they'd have access to in their roles as advisors for the S-400 missile system.
