Code what?

Under General > Miscellaneous Information, on the Miscellaneous tab, under the Final Return section, check the box for Final return.

If you have problem finding what you need, you can also use the handy free text search box on the left.  It's quite accurate for the most part.  Give that a try.

Thanks but I wanted to know how to code a final Limited Partnership to force the loss carryovers to use.

It helps to be explicit about what you need.

If you are referring to the partner's individual return and those are suspended passive losses, go to Income > Passthrough K-1's > Partnership Info (1065 K-1).  On the tab of the partnership in question, under Part I - Information About the Partnership, scroll down to the line Delete next year (final K-1, free prior unallowed passive losses) and check the box.
