hi
I passed throuh this same problem. I filed Four Revise return.You can file Only Revise Return.you Cant change original FVU file. You must Enter in your software date of filling of Return On return No. and then click on a button which is showing revise return.you Can t change in Q4. in this all tds entries are blocked. First you would do a work. bring all entries in same positions as it is before than after filing correction statment , do all changes whatever u want. revise return can be filled without int with in 90 days of filing of original return. after that it attracts penalty. your revise return will show you only corrected figures not all .
for any query, please mail me.
