Mr Sourav Amendment of invoices of 2019-20 is possible till 31.3.2021.
Mr Jagan Iam assuming you want to reduce the tax payable amount in these invoices, in my opinion you should upload credit notes against these invoices to get the benefit in the next gstr1 and reduce your liability in GSTR3B
I hope this helps
