My sister-in-law passed in September 2020. I'm her PR (personal representative). I have the paperwork to confirm this status. I know she filed taxes with Turbo Tax in 2015, 2016 and 2017. I don't know if she filed 2018 and 2019 taxes. I don't have her current login and password information to check. How do I proceed to determine if she did file in one or both years?
Thank you in advance for helping navigate this challenge.
