I don't understand why you were hit by a car if you were turning? I would have thrown a fucking fit on scene if she pulled that shit. Why was she hanging around if she wasn't in the wrong?

Anyway, if you have any of her information (you should, if not, call the officer directly and demand it), and you can tell your insurance claims adjuster what happened. They may or may not bring her into the claim, since she didn't actually have contact with anyone. However, she DID directly enter your space and you had to take evasive actions in order to avoid an accident. I don't think you are 100% not at fault, but I could see how all 3 drivers in the accident could share in the liability here.

I'm very glad you, and especially your kid are okay.

EDIT: Never mind about my first question, I worked it out. However, that does make you any where from partially - 100% at fault. At this point, it really is going to rely on how good of claims adjuster you get. Fortunately for you, it doesn't matter a bit what the cop said or who he wrote the ticket to. Since you and the lady have different stories, your insurance company should defer to defending you, unless your story is full of holes and obviously a lie or something.
