have H1 Valid till Nov and Extension From Dec 2016 - What to fill in DS 160

Have Approved H1B’s. First H1B from same Org till Nov 2016 and Extension from Dec 2016. When I prepared my DS 160 and submitted I have put the current one. When scheduling appointment Dates, it is showing up Dec 9th. Should put the Receipt number of the extension? Appreciate if you can clarify me this.
