@lahalahalhahhh Every amount that TurboTax generates is based off of what's entered on the tax return, unless the number is something specified from the CRA (ex: in a formula). There are 3 ways that information can be entered into a return: Direct entry from the user, CRA Auto-Fill or transfer of info from the previous year's return. So, yes, it's possible for TurboTax to calculate something based on something that you didn't manually enter, but it would still be using information that you allowed the program to import.
