You need to do a separate return for each year. TurboTax prior year taxes can be found here. You will need to start with the oldest year to this year's return. Here you will find the link to our TurboTax Online versions for 2019.

If you need to complete any year prior to 2014 you will need to get them from the CRA website- print them and do them by hand. 

Please note, that you will need to print to mail your returns that are prior to 2016.
