What is the due date file TDS return pending for the month of March?

There is no extension for payment of March month TDS. Due date still remains at April 30, 2020. However, where TDS is paid after the due date, instead of existing penal interest rate of 1% p.m (12% p.a), a lower rate of 0.75%(9% p.a) will have to be paid.

However, TDS returns can be filed till June 30, 2020 without any late fees

Is there any notification for the Tds return?

It is based on the ordinance passed recently. You can access through this link

Due Dates for Action based compliances like filing of TDS return has been expressly extended to June 30, 2020 by the Taxation and other Laws (Relaxation of Certain Provisions) Ordinance, 2020. Refer section 3(1) of the Taxation and other Laws (Relaxation of Certain Provisions) Ordinance, 2020 

Hence once the due date gets extended, there is no question of late fees u/s 234E. This waiver of late fees is consequential.
