Once 143 1 order is passed, you can not revise ITR, only rectification under 154 , now you can submit rectification under offline writed data correction where you can not add new income or deductions.
In your case wait till on line rectification starts, now tab is not available or you forget paying more taxes as order already passed and you got refund also.
From next AY 22-23 you won't be able to do mistake as new AIS form it will calculate all and prefile Jason ITR form you will get all details prefilled off line and on line filling.
AIS form will replace 26AS it will show fix intrest, saving intrest, shares and MF traded, devident received, Taxes paid etc.
