How do you disable TurboTax auto filling Quebec Schedule B for persons living alone (it ignores the personal info setting for eligible for amt persons living alone)?

You can't disable Schedule B, as it is used to calculate some refundable and non-refundable credit amounts that can be claimed on your Quebec return, like the Amount for a person living alone.

 

This is an automatic calculation if, throughout 2024, you maintained and ordinarily resided in a dwelling in which you lived:

• alone (that is, you did not share your dwelling at any time in 2024 with another person, such as a co-tenant, your mother or father, or a sister or brother)
• only with one or more people under 18, or one or more of your children, grandchildren or great-grandchildren 18 or older who were full-time students pursuing vocational training at the secondary level or post-secondary studies for which they received an RL-8 slip with an amount in box A

 

If you should not claim this amount and it is shown on your Quebec return, we suggest you review the information you entered.
 

Thank you for choosing TurboTax.
