Bacon sails is the g0-to place for used sails.  They may have something for a Turnabout.  For a boat that small you do not want “another sail that will fit”.  It will be too big or too small and be a major hassle to make work. The Turnabout Facebook page seems to be little used but there may be someone there who can give you other leads. Any sailmaker would probably be happy to make you a new sail.
