In 2023 I withdrew money from my HSA, it should be tax free, it is meant to cover 2020 medical expenses. Why is my Federal Tax Due increasing when I enter the amount?

I am itemizing medical expenses for 2023, but it appears TurboTax is treating my HSA withdrawal to 2023 medical expenses, thus my medical deduction appears to be reduced by my HSA withdrawal. The problem is, the withdrawal is for 2020 expenses, but TurboTax behaves as if it were applied to 2023 expenses.
