The anwer you gave was incomplete.
TurboTax does not allow me to enter the date sold or disposed (1c) from 2019 as stated on my 1099B.
I have a 1099B from 2020 for unclaimed property that was sold or disposed by the state of Wisconsin in 2019.
How do I get Turbotax to allow me to input a date from 2019 in bloc 1c?
