This question has been answered on the post: Call Options.If the transaction occured in a previous year, go to the A/L screen and enter the necessary transaction information.The A/L screen should show:
- a negative cost basis
- a negative tax basis
- a negative unit/share quantity
- a positive proceeds
- a Traded options/warrants format type
The cost basis, tax basis, and units are negative because you haven't really "sold" that asset, only the option to sell the underlying shares.
The proceeds received at the time of the option transaction is a positive number as the funds were actually received.
The format type is "Traded Options/Warrants".
