I don’t believe you will have to mail a paper copy as TurboTax will get rid of all the errors when you do it my way. When you place a zero in the cost basis and positive number in the proceeds you still will end up with a negative loss. You can see this in the table below the entry form in TurboTax. Simple math. Again, it would’ve been nice if the brokerage firms had read the new IRS code and fixed their output for the TurboTax import.
