I sold an investment in 2020 that was purchased in 1987 and I just discovered after I already submitted my State Tax 140 to AZ, that I had an error computed by Turbo Tax on this very issue. Turbo Tax entered the my long term capital gains in the special capital gains treatment for property "purchased after December 31, 2011" which I am not eligable for. Please be sure to check your state to insure this did not happen to you because I have to amend now. Thank goodness it only resulted in a lower refund.
