Where do I add the amount of money I paid for 2014's federal tax while filing for my 2015's?

I paid my bill from the IRS from my 2014's, but I paid it in 2015. It was a large sum so I want to know where do I include this amount while filing my 2015 taxes?

Federal tax paid for a prior year is not deductible and is not entered on your federal tax return at all.
