I have some unused tuition fee in 2021, 2022 and 2023, how can i use them to reduce my payable tax, I paid like 1000 of tax and I thought they would automatically do it

If you have any tuition fees carried forward- TurboTax will use what you have to bring down the amount owing. If you feel it isn't working-contact our phone support so they can view your screen to see what the issue might be. 

Thank you for choosing TurboTax.
