Irrevocable trust will terminate spring, 2022. When do I file the final 1041?

I am the sole beneficiary and trustee for an irrevocable trust and I am filing a 1041 this April for the 2021 year. However, the trust will terminate in May 2022 so my question is: do I file a short year return after the trust terminates using the turbotax program for 2021 or do I wait till 2023 to file the final return using next year's program?
