TDS remitted shows wrong amount in 26AS

My friend has deducted Rs.50,050 as TDS from building Contractor for payment of Rs.10,01,000 at 5% and remitted online. The TDS challan shows these amounts correctly. But the contractor says he has TDS credit of Rs.1,010 only. My friend's 26AS shows Rs.50,050 as Transaction amount and Rs.1,010 as TDS on this amount. How this error could be rectified.
