Tds late payment

Sir / mam

I have filed the q3 26q returm of FY 2016 - 2017 on Jan 8th 2017.

I have got a demand from traces for delayed payment in tds on 12th december 2016 instead of due date is 7th december 2016.

i have paid the amount under the head 400.

If i loginto my traces portal. I could see both outstanding demand as well as uncoumsed challan.

Kindly clarify me the procedure to link demand and unconsumsed Challan.

Thanks in advance
