State tax filing

I do not have an underpayment of $800 - my total taxes due is $800 and I paid it in the first quarter. Under the Federal “Taxes, Licenses, and Fees” it has a box to enter State Income Taxes and that is where I entered the $800 payment. You are suggesting I delete this and only enter it in the State section? Then why is there a box for it in the Federal section and would it not be a deductible item on my Federal business taxes?

 

Thanks, Joe
