How to: Claim unused RRSP contributions from prior year?????????

I have unused RRSP contributions from prior year i need to claim this year, but TurbroTax offers no place to do that. Help documents lead to nowhere:
The information on this Help Link doesn't provide details on how to "Select the applicable option for instructions on how to claim unused RRSP contributions."
