Need to file Schedule C, have a k-1 and a w-2. Which product do i need?

[Jim1990]

Is there a single software that can process all these at once?

If you use the online version you will need the self-employed program.

If you're going to use one of the downloaded or CD versions then any of them will do. Start with deluxe an upgrade if you feel the need for more assistance. If you do not have estate return to do then you can start with the basic program.
