What if, I do not submit ITR-V within 120 days ?

If you miss submitting your ITR-V within 120 days(or extended Due Date as notified by Income-tax Department), your e-filing will be considered as invalid. It means that it will be considered that you have not yet filed your return. In such case, you need to file a revised return and submit fresh signed ITR-V to CPC, Bangalore.
