When I e-filed my federal return & had to make a payment, TurboTax gave me several options of ways to pay. I could have the payment directly withdrawn from my bank account, pay by credit card, check by mail, or several installment options from the IRS. The installment option links you to the IRS website where you can apply to pay by installments. I paid by direct ACH withdrawal and TurboTax walked me through the steps. I entered the type of account the money was coming from (checking/savings), the bank routing number, the account number. You can also select the payment date as long as that date is the due date or earlier. Basically, just let TurboTax walk you through the steps. (I will assume the procedure would be the same for paying any State amount due as well.)
