It has nothing to do with living in Florida, since Florida has no state income tax. You are only going to file a federal tax return, so it is the federal income tax laws that you need to understand.
Unless you also have a qualifying child who you can claim as a dependent you cannot file as Head of Household. Your GF is not a qualifying dependent to allow you to file as HOH.
If your GF lived with you for the entire year in 2020 and did not have more than $4300 of her own income---not including Social Security----then she might be your "qualifying relative" who can be claimed as a dependent in order to get the $500 credit for other dependents and the 3rd stimulus payment of $1400. You cannot receive the 1st or 2nd EIP payments for claiming her. And if she can be claimed as your dependent, she cannot get any EIP payments herself, since dependents are not eligible to receive stimulus payments.

If you qualify as Head of Household, when you enter your filing status (single or married filing separately) into My Info, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.
