Thank you for your feedback; I am sure it is frustrating.
When you used "Auto-fill My Return," the CRA’s system likely flagged your husband as having a valid DTC on file because their internal records often lag or still associate the SIN with a multi-year approval, even if the expiration date has passed.
TurboTax Online often stores "transfer" amounts (such as the disability amount transferred from a spouse) in background forms (Schedules 2 and 5). Ticking the profile box is only a trigger; if the data is already in those background schedules, the software sometimes fails to clear those forms because the trigger was unticked.
It is quite common for Auto-fill to fail for certain slips early in March. Many employers and financial institutions have until the end of February to file, and the CRA can take 3–10 business days to process those into the Auto-fill system. Manual entry is often the only way to be 100% sure for the first few weeks of March.
