The first issue in your case is one of domicile. Did your domicile actually change in 2020?
New York's rule is that your New York domicile does not change until you can demonstrate with clear and convincing evidence that you have abandoned your New York domicile and established a new domicile outside New York State. This means shifting the focus of your life to the new location. It is not enough simply to file a certificate of domicile or register to vote in the new location. All aspects of a person’s life are considered in determining whether a person’s domicile has changed. https://www.tax.ny.gov/pit/file/nonresident-faqs.htm#income
If your domicile is still NY, for tax purposes you are still considered a resident of NY, and ALL your income is taxable by NY - regardless of how much time you spent in FL.
But if you did change your domicile to FL in 2020 per New York's rules, then for 2021 you are a non-resident of NY. NY can tax non-residents only on NY-source income. NY-source income includes earnings from work actually (physically) carried out in NY, as well as income earned remotely from a NY employer, unless the employee is working remotely for the employer's convenience, rather than their own. A FL resident with NY-source income must file a non-resident NY tax return.
With regard to your husband's 1099, what is the date printed on the 1099? If the printed date is 2020, it should have been included on your 2020 tax returns.
The TT question about "living in another state" should be answered "Yes" only if you changed your state of domicile during the tax year. If you had the same domicile all year, but earned money in a non-resident state, you would answer that particular question "No", but you would answer Yes when the program asks if you had income from another state.
