For quota purposes, No Answer, Don't Know, Refused, and Other Specify are treated as ordinary categorical responses. When you set up quotas for a question that allows these responses, you must specify targets for these responses, and all interviews in a category will be terminated once the sum of pending and completed interviews matches the target.

If you do not want to quota on these responses, you can either set a very large target for each one, or set no quota at all, or you can accept the default target and flag these quota cells as being counter quotas only. See Overquota and counter quotas for more information.
