what box ?
if it's the small square other income box the double -click doesn't apply that's only to for schedule C or F.
if it is c or f - put the mouse pointer in the rectangular box (should be pink or red) then double-click. you should see a new window. highlight the form with your mouse and then click on ink. this only fills in the info you provided and creates a schedule C or F (don't use the wks) which you must highlight with your mouse to complete
hope this helps.
