Dear Sirs,  One of my client, for the month of Mar-20 & Apr-20, NIL Returns have been filed due to COVID-19. Now during May-20, he issued some credit notes against original invoices which have been raised during Dec-2019, Jan-2020 and Feb-2020. There is no invoice raised during May-20 and only the said credit notes have been issued due to COVID-19. Now, I have to claim the credit note amount which have been returned to customers by my client. I could not be claimed by way of deduction of credit note amount from sales amount. How can I filed 3B return for May-20 and claim the credit note amount. If I Net the Sales and Credit Notes, the negative figure has been arrived.

Kindly clarify the same. Thanking you Sirs, in advance.
