Okay.
What number should be represented in that field? There is no "Sales Price" field in a 1099-B. The field (I believe) is auto-calculated based on (Proceeds..1d) - (Cost Basis...1e) on the 1099-B for each of the individualize transactions. In my case I have 74 transactions pulled in from TD Ameritrade.
If you zero out the number (make a non-negative) your total capital gains goes UP and is not represented correctly, thus effecting your total return (which then become inaccurate).
You cannot zero out the number and complete an accurate representation of your 1099-B.
