I need to file out a 1120-H
Form 1120-H is included in TurboTax Business, but not any of the individual income tax preparation programs.
Further, in TurboTax Business the form needs to be prepared manually in Forms Mode (which means you are probably better off downloading and preparing the form yourself).
