If you are unsure of your residency status, you will need to contact the Canada Revenue Agency (CRA) and confirm it with them. 

If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency

Yeah, I got that information. Thanks!

Does Turbotax handle non-resident tax return? I bought a standard version, don't see that option though.

When you are asked to choose a province, you would choose non-resident instead.
