In TurboTax Canada, Line 40500 is an auto-calculated field. You cannot edit it directly on the final return because the software generates this number based on the data you entered in the "Foreign Income" or "T-Slip" sections.
Try these steps instead:
Search for "Foreign Tax Credit".
Go to the Foreign Tax Credit Worksheet (FTC).
Look for the specific entry for the USA and manually change the "Foreign Tax Paid" to $0 or change the "Net Foreign Income" to $0.
This will force the calculation engine to update Line 40500 to $0 without requiring an "override" (which would prevent Netfiling).
We suggest that you contact our Product Support team. They have access to tools we don't have here in Community, like screenshare, and can help resolve this issue for you.
