I'm not a tax expert, but the IRS "Instructions for Form1099-B" states on page 8:
"Box 1d. Proceeds
Enter the gross cash proceeds from all dispositions
(including short sales) of securities, commodities, options,
securities futures contracts, or forward contracts. Show a
loss, such as one from a closing transaction on a written
option or forward contract, as a negative amount by
enclosing it in parentheses."
This leads me to think if the TurboTax software would allow the use of parentheses, this would meet IRS requirements.
