If you are using TurboTax Online, there is no ability to directly edit the forms. You enter your information using the EasyStep Interview, and then TurboTax Online will populate the forms for you. You can see the forms by downloading/printing a copy of your return. You can also see the T1 line numbers by looking at your Detailed Tax Summary.
Please see the following TurboTax FAQs for instructions:
