I had exterior window installed, how do I figure out price of product?

[pameddleman]

I was given an amount to pay but how do I find just the price of the windows?

You should have a breakdown of the windows and labor. Contact the seller. Verify the windows qualify and the cost of the windows. Get them to send you a form with the price broken out for your tax records.

The cost of the windows is multiplied by 30% to calculate a maximum credit of $600 that goes against your tax liability.
