High Value Transactions Revised ITR

Due to some error in ITR-1 one person did not show interest from Savings Bank Account for F.Y. 2019-20. IT Deptt has processed the ITR and has refunded excess Tax deposited / deducted. But after that on site it is showing some savings bank interests (small amounts) as High Value Transactions which need to be shown.

Please guide how to show them in ITR-1 and revise it taking into account in original ITR-1 Amount to be Refunded (Excess TDS/Deposit) is shown, IT Deptt has refunded excess Tax with Interest and with these transactions some more tax with penalty will arise. Where to show refunded amount with interest, etc also.

Please help.
