Editing actual forms

[DoninGA]

If you are using the TurboTax online editions you do not have access to any forms, schedules or worksheets.

If you are using the TurboTax desktop editions, click on Forms

Any changes you make to any calculated field on a form, schedule or worksheet will void the TurboTax Accuracy Guarantee and prevent the tax return from being e-filed

You can only access and edit the actual forms in the Desktop program.   Are you using the Online version?   You have to fix  or edit by going through the interview questions.  What do you want to change?

You can’t replace (override) a calculated amount on forms using TurboTax Online. You can only override in TurboTax Desktop.

Refer to the TurboTax article How do I override (replace) an amount calculated by TurboTax? for step by step instructions.
