Credits and deductions

Hi Susan would you be able to advise in this regarding entering the RRSP contribution amounts, I am a bit confused 

FOR EG.

TAX file for 2018

Issuer of RRSP;  X Employer
Contributions for 2018 : $1000
Contributions for the First 60 Days of 2019 : $2000
 
TAX file for 2019
Issuer of RRSP;  X Employer
Contributions for 2019 : $2000 ( This amount is the same as I already entered in my tax file 2018, can I still repeat enter this amount under 2019 ?)
Contributions for the First 60 Days of 2020 : $1000
 
Does the above look legal and correct
I hope this makes sense
Thank you
Joseph
