One thing not yet mentioned. So I'll mention it here.
TurboTax Business (different from Home & Business) is required to complete the 1065 partnership return. TurboTax Business is not available as an online product or for MACs. It's for the Windows operating system only. Last I checked, and @AmyC can confirm, live help (TurboTax Live) was not available for any of the CD/desktop products.
