Filing for my deceased father who was married.

My father passed away in 2024. I obtained an extension for his taxes.  He was married at the time of his death, but I am the personal representative for his estate and am starting to file his 2024 taxes with turbo tax (or at least prepare to file). I've been able to select that he is deceased, however I am asked if he was married. I believe his spouse filed  separately and not jointly. I'm assuming I should select that that he was married but filing separately. Thank you for your help!
