TDS and 26AS

Dear,

Here, as you said the deductor (your client) has filed the return wrongly, the same return should be revised by the deductor.

But if he doesn't revise the TDS return, can I still claim refund of tax deducted by him, by filing my ITR. 

The deductor is bound to correct the return & deliver you the Form 16A.

YES, The deductor is bound to correct the return & deliver you the Form 16A., Otherwise he will be penalised

He has already given me Form 16 A, that shows tax deducted under Sec 194 J. It is only in my 26AS on internet that it shows that one of my tax has been deducted u/s 194 I.
