Can you manually edit any of the forms?

That's called an override.

turboTax Online does not let you do it.

TurboTax CD/download does allow it.

You will not be able to e-File.

You'll have to file a paper return.

Okay. Do you know how to get line 32A on Schedule C to be checked?!

This software gets worse every year!

So far this year I have run into the following problems:

when entering data into a 1099-R, Turbo tax exits

I have two 1099-R's from the same company, I can't enter any data into the second 1099

Imports from several brokerages don't work requiring manual input

You can edit a form if you are using the CD/Download. Please see this Turbo Tax help article for more information.
How do I switch to Forms Mode in the TurboTax for Windows software?
