Where do you enter the RRSP information if an employer has made the RRSP contribution directly, therefore gross income and no tax deduction?

When someone makes an RRSP Contribution on your behalf, you should still receive an RRSP Contribution Slip in your name and can report it as a current year RRSP contribution. If you have not received this slip, you should inquire with your employer if this is indeed an "RRSP" which was contributed to. You may also be able to access the slip through CRA.
