Try these steps below to troubleshoot.

Switch to Forms Mode by clicking the Forms icon at the bottom or top of your screen.

Open the "ID" form: On the left-hand list of forms, locate and select "ID" (Identification and Personal Information).

Find the residency section: Scroll down to the section titled "Residency Information" or something similar.

Look for the "Date of Entry":  * If a date appears in the "Date of Entry" field, right-click it and choose "Clear" or "Remove Override."

Check the "Residency Status" section. It should be coded as "1" (Resident) for citizens. If it is coded as "4" (Immigrant), set it back to 1.

Check "World Income" (Schedule A): See the list of forms on the left for "Schedule A" or "World Income Worksheet." If it's there, open it and make sure it's blank. Delete any unnecessary information.

If it still doesn't fix the issue as per the product support, you do have to print and mail the return to CRA. 

Hope this helps!

Your process changes my status to a full-year resident. But I only entered Canada on Sept 1, 2025. And the workesheet shows my status as immigrant and Canadian resident. But NETFILE still gives tis error:

@dwpmr Did you choose a non-resident option instead of a province? When you spoke to the CRA, did you confirm your date of entry and your residency status?
