If an exchange-traded stock option is sold short and the option expires, the seller pockets the premium received. The "Proceeds" (1099-B box 1d) shows the premium received when selling the options short, and the "Cost or other basis (box 1e)" is ZERO.
But TT (desktop) will not accept this. If I change "Sold or expired?" to "Expired" it still stays there is an error.
There are many, many questions and half-answers about this, but no definitive answer that I've found. HOW can imported option trades be fixed so TT will accept a zero basis (or "Expired")?
