Two or more Form 1095-A's are linked to multiple businesses for self-employment health insurance purposes. ProConnect Tax doesn't support linking self-employed health insurance to multiple businesses. (ref. #43487)

How do I resolve this diagnostic?

Do the following to resolve this diagnostic:

• Make sure the Schedule C activities (businesses) are marked correctly for the taxpayer or spouse. If both activities are marked as Taxpayer—or both activities are marked as Spouse—the diagnostic will continue to generate.
• On Input Return ⮕ Deductions ⮕ Adjustments to Income, check for any entries in the SE Health Insurance section. Remove any entries in the Net Earnings (if multiple businesses) field (if only 1 business is present).
