Amend itr-2 before sending itr-v

S. 139(5) allows revision of return only if return has been filed u/s 139(1) [i.e within due date] or in pursuance of a notice u/s 142(1). Therefore belated return can not be revised

For rectification u/s 154, you need to enter communication reference no. , i.e any intimation u/s143(1). Without it you can not rectify.

Therefore wait till you receive demand notice/intimation u/s 143(1)

Since you forgot to include income so your tax might also be higher,consequentrly there may be interest liabilities.
