Hii Gopi!
Unfortunately, There is no correction facility available for IISC 2020 Application forms. You needed to Fill the form carefully. And, as you must be knowing, the admission to the Institute is provided on the basis of Jee Mains and KVPY marks and there is no Entrance Test any further.
You may try contacting the official helpdesk and ask them about the same. They may help you or provide you the çhance to make corrections.
Hope this helps.
Good luck!
