Deductions & credits

In your answer you stated that:

"There is, however, an exception under the Canada-US tax treaty that allows a RRSP deduction in certain situations. In particular, if the RRSP contribution is made via employee contributions to an employer sponsored group RRSP plan, then the contribution is deductible on the US tax return."

I am US citizen that lives in Canada and I contribute to my Canadian employer sponsored group RRSP plan. Where can I claim this contribution in TurboTax?
