I have a client with 2000 in 2024 mass. tax liability. Witholding was 1200, leaving a balance of 800. They

received a refundable child tax credit of 440 and wrote a check for 360.  In checking 2025 schedule a line 5a the software carried over 800 as the total mass tax paid in 2024 treating the child credit  on the 2024 as a  mass tax payment. Is the software doing something incorrectly as I don't think client should be deducting more than they paid. Any ideas? Thanks!
