[Unused RRSP contributions previously reported and available to deduct for 2020]

Thank you everyone that responded. I appreciate your help. 

[Unused RRSP contributions previously reported and available to deduct for 2020]

Thank you very much Nawal. But I did not contribute to my RRSP last year at all. I don’t recall any other year where I may have contributed but not claimed. I can’t get a hold of anyone at Revenue Canada to answer this. If I claim this as a deduction will I be penalized later?  Thank you. 

[Unused RRSP contributions previously reported and available to deduct for 2020]

In my 2019 Notice of Assessment, the second last line says:  "Unused RRSP contributions previously reported and available to deduct for 2020".  And there is a positive amount for this line.  The final line "Available contribution room for 2020" indicates a positive number as well.  

I have already contributed just under the amount shown for the "Available contribution room".  But, I don't understand what to do for the "unused RRSP contributions..." amount.  Does this mean that I can contribute this amount, on top of what is shown for my final "Available contribution room"?  Or, Can I just claim this amount, without having to contribute, because it says "previously reported and available to deduct..."?

Thank you.
