Overspray on new car, total newbie

Hello! I don't know much about cars or detailing so I've run into an issue and don't know what to do about it, so if anyone has some kind advice I would really appreciate it!

I got a new car (2024 Toyota Corolla Hybrid) and had it for about a year now. I washed it a few times and used a sprayable wax that you put on when wet and then rub in with a microfiber cloth.

Recently I saw some people and they told me it looked like I had overspray on my car, and that someone was probably painting near me and it got on my vehicle. I've included pics, but it looks like a fine mist of whiteish beige droplets all on the front, back, and top of my black car, and not really on the sides. I have no idea who did this or when, but I live in an apartment complex and have seen them painting outside about a month before others pointed out my car (I don't look very hard at my car so I didn't notice it right away).

What should I do about this exactly? I saw a handwash carwash when I was out and stopped by to ask, and they also agreed it was overspray and that they would claybar the car for $150. Does this sound about right? The apartment complex has already refused to take accountability for this as there were no cameras and I didn't come to them right away, even though we both agreed we had no idea what date they were painting the complex, so I have to pay the cost myself and don't want to overpay somewhere for something I might not need. I'm fine to do the claybar if that's what needed! I did go through the carwash since I couldn't get out of the line and just did the cheapest wash and unfortunately nothing came off which I figured it wouldn't. Also, I've seen what looks like circular scratched(?) in the sunlight so I'm not sure if that's from these car washes.

TLDR: Overspray on new car, white specks and circular scratches, was quoted $150 for claybar, what should I do?

Thank you very much!
