itr v submission

Once revised return is filed, original ITR gets automatically invalidated. Only revised return is considered.

So, if there are any changes, you can file rectification request. Or even revise it again (applicable only for AY 2017-18)

You cannot change ITR while filing rectification u/s. 154. Any mistake which is apparent from the record in an order passed by the Assessing Officer can be rectified under section 154.
