State tax filing

Thank you for the quick response and the clarification!  So if she satisfied residency reqts for KY in 2020 by living there for more than 183 days (Jan thru Aug), but had not yet met FL residency reqts by year-end 2020, the only state of which she was a resident was KY.  Doesn't that make her a full-year KY resident?  If not, how should she file?  Thanks again.
