If you paid sales tax on the materials, and you are itemizing your deductions, you should go through the sales tax section of the deductions & credits portion of the program and enter your actual sales tax paid as it could increase your total itemized deductions.
If you will be taking the Standard Deduction, these items won't affect your tax return.
The other potential tax item here would be related to credits for certain energy efficient home improvements, but only if any of your improvements were qualified. For more information on these credits, see this article on the energy tax credit.
