Expired short options positions (covered calls) have a profit, but if I mark the option as expired I cannot enter the gain. Should I mark them as sold instead?

When corrected the various options transactions imported from my 1099, I am uncertain as to how expired options short position should be handled.  These would be covered calls, or written puts that expire.  These generate a profit, but if I mark the option as expired (using TT Premier) the gain is erased.  Should these be treated as Sold instead of Expired?  Does TurboTax assume that all Expired options were purchased by me, and not written by me?
