The tax ID was for my mother who died in 2018 and I filed form 1310. Now I have another 1099 div for her that was earned after her death in 2019 . The tax is in fact mine and the investment firm will not change the tax id to me. I tried to start a new tax return for my mother in 2019, but it asked for a date of death in 2019. So I can't move forward unless I change the date. Any suggestions on how to proceed? It feels like I need to fix something on her end and add it to my return.
