If you are using TurboTax Online, there is no ability to edit the actual forms. You can only see the forms when you print/download your return. Please see these TurboTax FAQs for instructions on how to print/download your return: How do I print/save a copy of my tax return (Online version)?
If you would prefer to prepare your returns by using the forms, you can do so with TurboTax CD/Download. You can see what we have available for 2021 on our website: TurboTax CD/Download for Windows
