Tax residency and obligation

[Alphapapa007]

I'm looking for some advice. i am a european citizen and I lived as a temporary worker in Canada for 3 and a half years. I left in 2019 to go backpacking, and filed a return, my notice of assessment has a note on it. "Emigrant".
For a variety of reasons in all of 2020 I didn't settle in any country, and spent a lot less than 183 days in any. So i haven't taken up tax residency anywhere new.
I earned a small amount of income during the year, from a non canadian source. Do i have a tax obligation in Canada, because i haven't taken up residency anywhere else and i am not Canadian?
I have received mixed advice on this so far.

And if i do, can I use turbotax to file? What residency would i choose?

Any help is appreciated.
