You can put any state you want on AMCAS, but state schools will require you to prove that you are a resident, which involves things like where you filed taxes, where your driver's licence is, where you vote, where you bank, where your possessions are, and what state you listed on your federal claim. I'm not sure what the rules are if you are supported by your parents and they are divorced in separate states, but I assume the parent you lived with before college is the one they look at.
The bottom line is that you are more likely to wind up with NO state considering you a resident than two, so apply where you really are a resident. Florida might give you special consideration for admission because your parents own property there, but they will not give you in-state tuition. (This was my situation, applying after moving away after college. I was a resident of NC, but had spent so much time and still had tax-paying relatives in SC, so SC schools considered me special for admissions but not for tuition.)
