What year 1041 form and tubotax version do i use

I am using the 2021 business edition on a 1041 for may late fathers estate, the fiscal year is Nov, 30 2020 to Oct,  31 2021 (initial return). The date field automatically inputs Nov, 1 2021 to Oct, 31 2022, can I overide this or should I be using the 2020 software edition? Also, should I be filing the year 2020 Form 1041 or the year 2021 form 1041 and using that years tax schedule? I have already filed for and extension (Form 7004).  Thank you
