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.
