Exactly what fees are you trying to pay? For an immigrant visa (CR-1), that would be the NVC processing fee and the Affidavit of Support fee....which are not applicable for K-1 cases.
For a K-1? What checklist? There is nothing to submit to NVC for a K-1. For a K-1, NVC simply assigns a DOS case number, then forwards the case to the consulate.
