I contributed to a spousal rrsp= . where do i enter that amount on our tax return.

When using TurboTax, click on the RRSP profile and put a checkmark next to "Made RRSP/SPP contributions during 2018 or the first 60 days of 2019".  You will be prompted to answer if you made any contributions to your spouse's RRSP account and to enter the necessary details.
