I need to file a 2555 form. There is piece of text on Line 9 that I was unable to change last year. Do I need the downloadable software in order to change this text?

I would definitely suggest the CD/Download version for TurboTax as you will have access to your tax forms while you are preparing your tax returns.  If you need to change text on a form, this is the version of TurboTax that you need.
