HSA Contributions--entered a dollar amount from W-2 but when finish the tax break section, showing up as $0 for 2024. How do I fix that?

You don't need to fix that.

Did you have an amount listed in Box 12 on your W-2 with Code W?

That indicates contributions were made BEFORE tax. 

Contributions made pre-tax are not used for a tax break because that was the tax break, they were made with pre-taxed (not taxed) dollars.
