if you don't have access to the "W" code then there is a dedicated way to enter a "disallowed loss" and TurboTax will insert Code W for you
When Box A or D and basis is incorrect, do not modify the cost basis.
use an adjustment with Code B to get the correct gain/loss with your true cost basis.
similarly for wash sales use an adjustment with Code W to enter the disallowed loss as a positive number in col (g)..
When Box B or E and the basis is incorrect, enter the true cost basis in column (e).
