Where do I enter my rrsp contributions from January 01, 2018 to March 01, 2018?

For an RRSP contribution made before March 2, 2018, report it in the tax return for the tax year in which you made the contribution. You can make changes after you have filed your tax return through the CRA or through ReFILE: https://turbotax.community.intuit.ca/replies/2647992

Here is how to enter RRSP contributions in TurboTax: https://turbotax.community.intuit.ca/questions/1190212-how-do-i-enter-rrsp-contributions-in-turbotax

For contributions to RRSP from Jan to March 2019, can they still be entered in the 2019 return?  If so, where do I add it in TurboTax? Thanks

Unfortunately, RRSP contributions made from January 1, 2019, and March 1, 2019, cannot be added to the 2019 tax year return. RRSP contributions don't follow a calendar year for tax purposes. If you have RRSP contributions made in the first 60 days of the following tax year, those contributions are entered on the previous year's tax return. In essence, those RRSP contributions should have been included in last year's tax return; in this case in your 2018 tax year return.

Not to worry. You can still claim the contributions. You'll just need to file an adjustment, which you can find out about in this link:
