Dear Sir

My Client have wrongly declared SEZ Tunover in GSTR 1 of Table 8A instead of Table 6A/6B

Now I am unable to file the refund application

what is other option to file the refund application

please note this refund related to FY 2020-21. ( I can't amend the invoices )

Please suggest me in this regard.
