There is no need for Form 16 as such if your employer has deposied the TDs and filed TDS return mentioning your correct PAN.
You can register for online view of your tax credit for 26AS at nsdl site. If you hve e-filed your return, such facility is also availiable on efiling site also.
Still you will need TAN of your employer for efiling of your return. You can get the same from form 26AS.
If your employer has not deposited the TDS even after deduction, he is a defaulter and you can make complaint against him with the relevant TDS authorities.
