In fact TurboTax version of California form 3840 side 2 has many errors:
1) For part 1 it places the 'OR' between the property description and address instead of between the address and parcel number
2) For part 1 it requires check boxes for all A/B/C even though there may be less than 3 properties
3) For part 2 all the properties are labelled as 'B'
4) For part 2 it again requires checkboxes for all three properties even though there could be less than 3
5) And as mentioned before, there is error checking enforcing Part III line 10 matches Part II line 8 which isn't necessarily the case if there are multiple copies of the form.
