You don't manually enter data into form 3800. You would enter information from other forms and information from those forms populate form 3800. For an example, if you need to add Form 3468, you would generate Form 3468 by going to Open Forms in the Forms mode in your return. You would enter information on that form and the information will flow to Form 3800.
Form 3800 gathers information from over a dozen different forms. Turbo Tax wants to make sure you fill out these other forms thus won't allow you to enter data on form 3800 itself.
As an FYI, if you are using Turbo Tax Online, you will need to switch to the Desktop product because many of these forms require a manual entry that isn't available in the online product.
