Challan form /itns number

 I e-filed IT return for A.Y. 2018-2019, e-verified and after processing the ITR-I some amount was refunded to my bank Ac. After e-filing and e-verification I found mistake in e-filing and within 3 days I submit revised ITR-I and pay online and e-verified. Now revised ITR-I has been processed by It dept. and I have received email for payment of amount (equal to refund amount). The payment  link in Pdf does not work and I go IT dept. website and ultimately redirected to NSDL website.There are many challan forms. Through which challan form should I pay the amount?
