Calculated field is not showing decimals even when this is set up.

3. Discount field does not show dollar sign and 2 places after the decimal even though I put that on the calculation options.

I've checked your JotForm see that the discount is set using a number field. Since it is a number field, it is not allowing to display $ symbol. The field is displaying decimal points as soon as the calculation values are entered. If you want to display $ symbol with the calculated value, you may consider using a text or Form Calculation widget instead of a number field.

Please see the demo form that can help you understand the differences.
