When submitting 2021 tax to CRA, message says, can't use it to set up My Account w/CRA. Need to do online 2019 & 2020 taxes still. Can I get around this?

If you have not submitted a tax return previously to the CRA then you will need to mail in your first return so that they can have everything on file for you. Then the following years you will be able to NetFile. 

Thank you for choosing TurboTax.
