suggestion for wrongly TDS payment

I think you'll have to revise both the returns. Although the amount cannot be split, however in both the returns you can show the actual amount paid corresponding to the less amount deducted. E.g If total payment is Rs.100 and Rs. 60 is pertaining to March quarter and Rs. 40 pertaining to June quarter, in March quarter show it as deducted Rs. 60 paid Rs. 100 and in June return show it as Rs.40 deducted and paid Rs. 100. Incase you receive a notice from department you can clarify the case. This is an genuine error. However pay the interest amount also beforehand.

The TDS should be deposited on the 7 of next month in which the amount has been credited or paid which ever is earlier. In case of TDS deducted on 31 march the cut off date is 31 may for which a seperate return is filied.

You have deposited TDS in June. So the amount would reflect in Apr to June return.The only default is  you havenot  paid the interest on late deposit with the amount of TDS amount.

There is no question of splitting the amount of the TDS for June.

You should pay the interest amount and just revise the apr - june return with int amount.You dont have to revise March return.
