Try using the "Delete a Form" tool to remove the Schedule K-1 from your list of federal AND state forms. If that doesn't work, update the state K-1 interview with "0"s for any income or expense items.

After deleting the Schedule K-1, log out of the program. When you log back in, use the Delete a Form tool to confirm the Schedule K-1 has been removed from the list of forms in your return. Then check the state interview to see if it is still expecting an update.
