Trust Final Return now or do I have to wait until all distributions are made.

I am the executor for my mothers estate.  She passed in 8/2022.  Siblings and I sold the house in early 2023.  I distributed most of proceeds, but held some back in case of taxes.  Can I file the final return for 2023, or do I have to file the final for 2024 since this is when I will pay the final distribution.  I do not expect any income or further taxes for the remaining balance.
