Medical Student On-Call Stipend in Box 28 T4A causing flag as self-employed

I went through my return as usual, but for my on call stipend, my T4A reported the amount in Box 28, and indicated "NO" when asked for box 28 if it was fees for service, and in the review section, I'm being given the warning "Your province of self-employment is different from your province of residence. TTO does not support Multijurisdictional returns. Review your entries."

 

Should I ignore this warning and continue with filing? I was not self-employed and am not registered as a business, this is a lump-sum payment received for on-call services required during 4th year of medical school.
