This is my first year filing with Turbo and I need a financial statement made with my last three years of tax returns. How do I acquire this info?

If you used TurboTax Online, sign in to TurboTax Online for the tax year 2018 here: https://ww1.2015.turbotaxonline.intuit.ca/ to view your 2018 income tax return.  As far as the information from your 2016 and 2017 returns, if you are registered for the CRA My Account service, you can log into your account and view the information there.  Otherwise, you can contact the Canada Revenue Agency at 1 800 959 8281 and they can provide with copies of your income tax returns.
