If you use TurboTax Desktop you can fill out one Schedule C using one of the spouses (does not matter which). Once the Schedule C is complete go to the Forms Mode, Go to Sch C and change the ownership question from Taxpayer or Spouse to Joint Venture. This creates one Sch C with both names and splits income on Sch SE, one for taxpayer and one for spouse. Thanks to JM for collaborating with me for this gem.
