Previous posts states TurboTax doesn't allow you to take this IRS credit when trying to estimate your 2023 tax bill until the IRS completes the form on or about 1/10/2024. However, I have another tax preparation software that has the form with the specific line for the costs of a heat pump water heater credit and allows an estimate of taxes, though they also state the form is not final yet. Unclear why TurboTax can't provide a current estimate as the IRS form is completed an available on their website and appears to be the same form in TurboTax 2023?
