The taxpayer passed in 2022, she only had 15k of social security income.  Does a final tax return need to be filed?  And if so, can it be filed electronically since it doesn't have any income?

A follow up question has to deal with her estate, she had a very limited estate but her brother opened up probate because there was a potential for a lawsuit on her death.  He is not going pursing any legal action and wishes to close out the estate.  Does a 1041 have to be filed for 2022 with zeros down the form, since probate was opened?
