I may have figured out how to work around this. In forms mode, go to box 3 for the 1099-MISC and check the "Medicaid waiver payments excludible from gross income" check box. This will change the error to "Other income checkboxes should not be checked when Box 3 other income boxes have been checked or one of the schedules have been linked." Then uncheck the box and the error will disappear. The form is still showing with a red exclamation mark in my forms list, but when you go to the form there is no error. Not sure if it will let me e-file or not (I'm a long way off from that), but it's progress at least.
