Fiduciary Returns for estate open for more than 1 year

I am the administrator of my father's estate.  He passed away in October 2023 and I obtained an FEIN with a fiscal year that ended 9/30/24.  

Due to some real-estate that I am trying to sell, the estate is still open, but closing for the sale of the real-estate now look like it will be in November.

My question is: I have filed the returns for the fiscal year ended 9/30/24.  If the real-estate transaction closes in November, can I file the final return on a 2023 1041 before the 2025, or do I have to wait until 2025 and file using the 2024 Form 1041?

 

Thanks
