how do I claim Jan-Feb 2019 rrsp contributions in 2019 rather than 2018
I've over contributed for 2018 IF I include contributions made in the first two months of 2019. My thinking is I don't need to claim all of the Jan-Feb 2019 contributions for 2018, so just claim what I need and use the rest as 2019 contributions. Can I do this? How?
