Contrubution to pension fund

I am working in a PSU. In FY 2018-19 my company revised the Pension scheme w.e.f 2007. And started Employer contribution @ 9.8% of basic+DA.w.e.f 2007. The employer deposited this as contribution in 2018-19 FY for 2007,2008 so on to the LIC.

What would be the tax treatment/liability of this money deposited to LIC in the current financial year.

Can i claim yearwise rebate of previous years towards pension contribution.
