1041-T missed deadline

[KFCPA]

First & Final 1041 return for my parent's trust with 645 election for fiscal year. Mother died mid-Nov 2022. First time preparing trust return and I didn't realize fiscal year must end October 31, 2023 and didn't realize 1041-T had to be filed within first 65 days after fiscal year end.  If fiscal year end can be 11/23/23, I'm still within the deadline. Suggestions?

Fiscal year could end 11/30/23. (beginning 12/1/2022)

From date of death to 11/30/22 was there enough income to require a 1041 be filed?

Sjrcpa: Thanks for your reply. Unfortunately, there was about $5K interest income for Nov.2022. Does the IRS accept late 1041-T if Final return?

I don't know but I doubt it.
