Once you move to Florida and abandon your New York residency, you will not pay NY income tax.
File a part-year New York return and report all income earned while you lived in NY, including the first four weeks while you worked remotely from NY.
The rest is Florida income. Florida has no income tax so you don’t have to file a state return.
Massachusetts does not tax nonresidents. None of your income is taxable to MA and you don’t have to file a MA return.
