Using desktop version. Father passed away in 2026, e-filing 2025 1040-SR (not the final year and an amount is owed). I inputted my father's date of death and my name for the Care of Representative's name.
When e-filing "Sign Your 2025 Return" whose PIN and Date of Birth do I use, my father's or mine. My father did not efile in the past so I'm guessing I can make a PIN up.
Also for "Additional ID verification" whose ID do I use, my father's or mine?
If the PIN, DOB, and ID are my father's information is there any additional information that I have to give besides my name as Care of Representative? The desktop version does not asked me for my information when e-filing.
Any help would be appreciated.
Thanks
