Yes, you will include the RRSP receipt. Is box 66 filled in on your T4? If so follow these directions:
Click the RRSP tab and RRSP profile.
select "Made RRSP contributions during 2017 or the first 60 days of 2018" and "Transfers to RRSPs"
Click through, entering info.... On the "Transfers to RRSPs/PRPPs" page, enter the amount from the T4 box 66
Sorry I just noticed you are using the desktop version. There is no transfer to rrsp button. Instead, on the RRSP entry page enter the amount on box 66 of your t4.
