I agree with Hawkeye, lots of good suggestions. It seems that your daughter is still acting like a balky adolescent - kind of a power struggle with you as adult/mom.
Probably time to both change your attitudes and see her as an adult sharing a home with you, not an adolescent you have to prod. Maybe have a discussion with both your kids, write up a contract of what your daughter will do in, including rent, in exchange for living there. It will be a rude shock for her if she has to move out and do everything on her own.
With your son, at 17 and with a license, he can be expected to pull his share. Maybe review co-dependence with an eye to the fact that your kids are now adults, or just about. My thought is that our job as parents is to help our kids grow up to be as self sufficient as they can be. I'd start by telling them that you are now three adults/semi-adults living together, and it is time for them to pull their weight.
