I have the same problem. The current answer does not help as my 1d value is positive. I've tried entering the total cost basis for my 1099-B statement including non-covered securities. However, TurboTax doubles my cost basis, which is not right. What value should I enter? Total covered and non-covered securities cost basis or total IRS reportable cost basis for covered securities. Is this the value that we are to check? Please clarify what is needed. Thank you.
