how to correctly enter state tax credit as state tax paid on Fed Sch A

how do you properly enter "charitable" payments that are state tax credits per Treas Reg 1.164-3(j) on Line 5, Sch A, as state taxes paid? The only answers are completely wrong that I found. You cannot enter them as charitable deductions on Fed Sch A.  Turbo Tax does not have a proper option for entering.  It appears the only way is to go to forms view, click on Tax Payments, and enter on Line 24 an amount paid (which TT calls "other" and refers to amended returns, installments, etc), but this isn't correct either because it says the payment is for "prior year" taxes.  These payments are not estimated payments or withholdings or any other option in TT.  TT clearly needs to add a new box to properly account for payments made in accordance with Treas Reg 1.164-3(j).
