Filed an 4868 extension for married couple TY 2024 in April 2025; husband primary taxpayer; wife is spouse.

Before 2024 return could be completed, husband dies ( 5/11/25).

Return now ready to be finalized.

Can the return still be filed with husband as primary ( deceased); wife as spouse or do I have to redo the inputs and file with the spouse now as primary taxpayer;  husband as spouse.??

And what about TY 2025?  She will still be able to file MFJ.   Will the order of primary/secondary taxpayer matter as well?

Thanks for any insights.  All be well!
