Regarding IRC Sec 645 election, when is Form 8855 due exactly?

I have read that Form 8855 is due by the first estate income tax due date.  So, since estate income tax operates on a fiscal year, if the decedent passed on 9/16/2020, then the end of the fiscal year is 8/31/2021, correct?  And taxes are due by 12/15/2021.  So, does this mean that the 1041 along with the IRC Sec 645 option and Form 8855 attached is not due until 12/15/2021?  Do I not need to do anything by this 5/17/2021 calendar date?  I don't need to file th eForm 8855  by 5/17/2021?  I am not ready to fille 1041 - have not completed distribution of trust assets.  Note this was a QRT, and all assets in trust, nothing in estate/probate.  No probate.  Trust is straightforward, but it will have income.  Can I do nothing at the IRS level until 12/15/2021 and just work on getting everything handed off to beneficiaries such that nothing remains that is owned by the TIN?  Thanks.
