How to clear or edit the declaration that was made? 

To view or edit all the declarations you have made and to make any changes or add additional declarations go to the Manage Tax (1) tab, you will be directed to the first tab under that, i.e. Declaration (2) under which you will further be directed to the My Declarations (3) tab, where you will be able to view all declarations done by you under various sections and approved/accepted by the concerned administrators.

The various sections (4) under which you can add declarations are adjacent to the My Declarations tab. You can select the respective section under which you want to add a particular declaration.

Under My Declarations you will be able to view all declarations done by you under various sections, the number of declarations done per section, the amounts declared, the amount accepted, etc.

To make a declaration, go to the desired section (1), then scroll to the deduction name (2) under which you wish to make a declaration, and click on Edit Declaration (2).

Now, type in the declaration amount (1) and upload any attachments as proof (2) if necessary, and then click on Save (3).

You will now get a Success notification. Follow the same steps to add a declaration under any of the other sections.
