Difference of Flipkart entries in 26AS Vs AIS

My client sells its goods through Flipkart.  In Form 26AS, TDS are deducted by Flipkart on Rs. 60L but in its GST Return (details provided by Flipkart) Sales showing only Rs. 30L. What is the reason of the same and how we file ITR of this (As per 26As or as per AIS).
