If you didn’t use TurboTax in 2017, you can’t use
it to ReFile. You also can’t import tax return files from other software into
TurboTax. If you need to make adjustments to your 2017 return, you can do it
through CRA’s My Account service. https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/change...
