My aunt died on 2/22/2018. Inherited stock from her was put into my account on June 27, 2018. I sold the stock in 2020. In looking at the 1099-B i noticed that some of the stock i inherited was acquired in May of 2018 i.e. between the date of my aunt's death and the date i came into possession of the stock (i am assuming her money manager was continuing to manage her account and that is how the May 2018 purchase was made). So what date do i use as a cost basis for the stock acquired after my aunt's death but before i was in possession of it?
