Email from TurboTax: It's not too late to impact next year's taxes. What is TurboTax recommending?

Usually there is a link in the email that goes to a page with more information.

But most likely it's referring to RRSPs - this TurboTax Blog has information on RRSPs and how they can help reduce the amount of tax you owe on your tax return: https://turbotax.intuit.ca/tips/rrsps-and-your-tax-return-the-bottom-line-3892
