A small-sized pvt ltd company obtained PTRC & PTEC registration in June 2019 but never made any payments. Now they have been able to make payments for FY 2019-20 until February 2020. However, they are facing an issue while trying to pay for March 2020. The period of April 2020 does not appear under FY 2019-20, and when changing to FY 2020-21, it only shows the period of April 2020-March 2021. How should they proceed with the payment for March 2020?
