We have filed ITR-6 for the Ay 2020-21 ( Year ending March 20 ). One of our deductor has not as yet filed the TDS Return and has informed us that in the month of April 2021 the said TDS Return shall be filed. Now in such circumstances can we revise the said ITR-6 by typing manually the required TDS credit for the Ay 20-21 or whether the same can be claimed for the Ay 2021-22. Please guide me and oblige.
