Dear Sir, Instead of IGST against a tax invoice related to FY 2018-19 , I have booked ITC under CGST and SGST. This mistake identified later on in march2020. Now I have reversed the excess credit taken under CGST & SGST . But Sir my question is that , can I avail the credit of IGST now in March 2020 GSTR-3B return?? If not then can I claim refund of IGST as such is reflecting in my GSTR-2A and earlier was mere a mistake.
