Hi @max_gravel !
You can enter your RRSP information in two ways:
1) As a separate tax slip. Once you have inputted your T4 return, you can select "Add RRSP" and input the information from your your T4 RRSP slip
2) Manually enter the information on line 20800 of your T4 if your RRSP was deducted through your workplace.

Hope this is helpful!
