Your federal refund and your state tax due are completely separate from each other. You cannot pay the state from a federal refund, nor can you pay federal tax due from a state refund. Those tax returns went to two completely separate entities. If the state says that you owe, then you will have to sort that out with the state.
If you owe federal tax then you have to pay the IRS.
TurboTax gets no information from the IRS or your state after you file your tax return so TT will not know if the IRS or the state changed something on your tax return.
If you have federal tax due you can pay by mailing your payment with the 1040V voucher, (which has the address printed on it, having the payment taken out of a designated bank account, or you can pay directly on the IRS website.

You must pay your state tax due using the state’s preferred method of receiving payment. For most states that will be by making a payment to the state’s own tax website, or by mailing a check or money order.
