Line 12000 - Glitch?

Hi - There appears to be a software glitch in the 2024 income tax software.  I have reported NO Dividend amounts in the return, yet an amount of money automatically appears at line 12000.  I have called and spent the last 45 minutes trying to get this resolved, and no-one there seems to be able to override this glitch in the system.   Please HELP!!   

Thank you.
