TurboTax calculates the credit correctly provided that you enter everything correctly into TurboTax. If you are seeing a difference between H&R Block's software and TurboTax, you've apparently entered something differently between the two.
For example, perhaps you were a full-time student and you failed to tell H&R Block that. Or maybe you failed to enter your qualifying retirement contributions into TurboTax. Another possibility is that you or your spouse received a retirement distribution in 2021, 2022, 2023 or 2024 that you told TurboTax about but failed to tell H&R Block about.
