As VolvoGirl said, start your 2024 tax return from scratch, without transferring information from your 2023 joint tax return.
Filing status and marital status are two different things. You do not enter your filing status in TurboTax. TurboTax will ask for your marital status. If you did not remarry before the end of 2024, select "divorced." After you enter some additional questions, TurboTax will recommend the best filing status for you.
