I have a related issue.
I have a stock sale with a reported cost basis.
I need to change the cost basis to zero.
I check the box for "The cost basis on my statement is incorrect"
I input a cost of 0.00 and value is accepted but ultimately turbotax premier includes the original reported cost basis in all calculations.
If the cost basis is not reported and I change it to a value in using the cost basis is incorrect box it works....
