Annual Return 9 for fy 20-21 for quarterly return cases

I have entered GSTR1 returns quarterly and 3 B monthly for FY 20-21. by mistake my option was set to monthly. In the month of June I have entered GSTR1 invoices for Apri May and June

When I go for filing Annual return 9 it prompts me to complete filing of all returns before you can file Annual returnb  9.

If again I enter April detail  which are entered  in June it will cause duplication.

Kindly advise how to file Annual Return
