If you are talking about "Your personal info / 2. Tell us the state(s) you lived in" section then only enter "Florida" under the question "State of residence (on December 31, 2018)". Answer "no" to the question "I lived in another state in 2018" unless you changed your State of legal residence with the military in 2018. This way TurboTax will correctly use your Home of record/ state of legal residence. You will not have to enter the date you established residence if you kept your Florida state of legal residence for the whole year.
