I just got off the phone with TurboTax regarding a return not eligible for electronic filing because it contains Schedule C. TurboTax acknowledged that they are aware of internal issues with Schedule C and they are actively working on a solution with the IRS. At this time, returns containing Schedule C will undoubtedly display a "not eligible for e-filing" message (federal and state, if applicable). Both TurboTax and ProSeries are Intuit softwares. Hopefully, the problem will be resolved sooner than later.
