SEZ Sales refund Matter

sir,

we have made SEZ sales ( With LUT ) during Financial Year 2020-21 and 2021-22
while filing GSTR 1 for said Financial Year turnover of SEZ sales is shown in Column No 8A instead of 4A of GSTR1

due this mistake we are unable to file RFD 01A Application for refund

while preparing Statement 4 in RFD 01A it's showing error that ' Data is not available in GSTR1'

kindly provide any solution for above matter
