I'm having the same issue reported in this thread with TurboTax 2021 not allowing me to edit Schedule D (form 8949 extension) where I need to enter the word "INHERITED" in column(b) date of acquisition due to a qualified step-up cost basis event. TT appears to only accept date codes in the step-by-step query for this info. In my case it is for the sale of a home (1099-S) and do not have a 1099B worksheet to edit as suggested in this thread to fix the issue. Please help.
