Hi Geo123,
I have the same problem exactly and did the solution as you stated above; however, I have a doubt as I still have an outstanding RRSP receipt with the same amount which I did not enter into Ufile. If I do enter this amount as a RRSP contribution into Ufile, what I find is I now look like I've contributed this amount towards my RRSP, it takes up my RRSP room and makes it look like I've over contributed.
So to clarify, you're stating after performing your steps for the T4RIF, ignore the RRSP contribution slip and we're done?
Thanks.
