If you are using TurboTax Online, when it asks what province you are in, answer Non-resident. Then when it asks if you moved/changed provinces in 2022, say no. TurboTax will generate a non-resident form for you, as a person who was non-resident for the whole year.
If you need to fill out forms for BC, then unfortunately, you'll have to get the forms from the CRA and fill them out, as TurboTax will only allow you to pick non-resident OR a province.
