Can I use this program to file my 2021 return prior to my 2022 return?

Yes, you can definitely file previous years' tax return using the same methods you would use to file your return on time. You can file your 2021 tax return by going to this TurboTax webpage: File past years' taxes. For 2022 filing, you need to go to use a different return by going to this link: https://ww1.2022.turbotaxonline.intuit.ca/signin?

Thank you for choosing TurboTax!
