if you miss submitting your ITR-V within 120 days, your e-filing will be considered as null and void. It means that it will be considered that you have not yet filed your return. In such a case you will have to file revised return(if not revised then as the case may be) get a new ITR-V and submit the same within 120 days.
if above condition is not match then write to concern AO or cpc
