Sir,

Sale reported in GSTR-3B of May 2020  Rs. 60 Crores instead of Rs. 60 Lacs due to removal paise dot wrongly. Our sale for the year 2020-21 is likely in the range of Rs. 10 crores so this can not be adjusted in the next months upto sep.2021. However correct sale was reported in GSTR-1.

Moreover GSTR-3B do not allow minus figures.
Can we claim refund of such excess paid tax? If available under which refund head we can apply?
