I need to file the last 4 years and I'm not sure if I can do it on turbo tax

You can certainly use TurboTax software to file your previous year's taxes. Here is the link to purchase, prepare, and file your prior-year returns with TurboTax: https://turbotax.intuit.ca/tax/software/prior-year-taxes.

Thank you for choosing TurboTax.
