I would like to amend father's tax return to enter a change in cost basis and depreciation for a rental residence when his spouse died 2 years ago 2017 in California.
Father recently passed away 2019.
I would like to amend for him for 2017 and 2018.
I understand how to amend for change in cost basis and depreciation for 2017 and then carry through for 2018.
However, who should sign the amended returns?
There should be a refund, and I am wondering how to get this refund into his estate?
