ASKING TO RETURN TDS AFTER E FILING

First things, if it's relating to A.Y 2018-19, than you can not file return for that A.Y, because due date is already Passed.

Second, if You was agreed for 2,00,000 consideration, than are you received Rs.2,00,000 or 1,80,000 in cheque.??

Note: As per law, You're are suppose to receive Rs.1,80,000 in cheque after deduction of Rs.20,000 and after filing your return you get that 20,000 So, you received total Rs. 2,00,000 in this way. (Not required to give anything return because you received what you agreed)
