2024 AGI is 161,047, I paid more than 6,000 child care expenses for 2 dependents. I would expect the tax credit to be 6,000X20%=1,200, however, TurboTax calculates $835.

Want to understand TurboTax calc for 2024 tax credit. In 2023 it was straight forward, AGI of 149K with child care expenses of 5,800. Tax credit was 5,800X20%=1,160. What's the difference in 2024?
