State tax filing

Hi Tom.   I also have a non-covered stock sale due to a "reverse stock split". this would have to be a Long-term non-covered basis because this was acquired over 40 years and I did not actively purchase it, it was given to me as an employee benefit for the company (GE). It is just a small amount of stock, 15 shares. I have no idea what the requisition date was....1981, 1982?  Is it okay to estimate the date in the Turbo tax? I will also take your advice and use $0 as the cost basis, since I have NO clue.
