Critter, I am sorry to tell you.. but you are wrong. We had just about the exact same situation happen to us and my thoughts exactly went to the same place this person's did --> Why didn't the Turbotax software catch this issue?!? I called Intuit and spoke with one of their tax professionals. The tax expert I spoke to was fully aware that CA regularly pursues non-CA residents to file a CA income tax return and pay CA income tax on any income that came from any business that resides in California .. even if the service is never performed inside the state of CA. It's the most ridiculous tax law out there (if you ask me), but it's legit. In any event, I got the Intuit tax expert to fill out an official request (case# 451943692) to have this problem fixed in the Turbotax software. Hopefully it'll be there for the 2019 tax version.
