I updated turbo tax 2017 but I need to do my 2016 tax returns. Do I have to download a new turbotax?

Yes. Each year’s edition of TurboTax only has the forms and information for only that one year. Here are the products that we have available for 2016: https://turbotax.intuit.ca/tax-software/prior-year-taxes.jsp#2016
