I am sorry to hear that you are
having this issue.
If you are single, you can double
check that you have selected the correct option. Select “Marital Status” from
the “Setting Up” tab. Choose the correct options and click the “Continue” button
to save your information.
If you separated or divorced in
2017, the CRA will still require your spouse’s information. https://turbotax.community.intuit.ca/replies/3425400
If you separated or divorced
before 2017, you need to say "No" to the question "Did you
separate from your spouse/partner in 2017?" on the “Marital Status” page.
