This is the only way many have tried and even succeeded. 1. After deleting the sec. 80U, save the tab. Validate the schedule, and close the utility. Open it again and go for last page.... or verification of ITR. Mostly the problem gets resolved. 2. Deselect the tab 80U which is by default selected and click on 'SELECT' option. So the amount will disappear. 3. Otherwise file ITR Online, with different browsers. These are hit and trial methods to crack the efiling.
Our bad luck the problem has not be resolved by ITD or program engineers even after reporting the error so many times.
