Do i have to apply my federal return to the amount i owe for state taxes?

No, that is impossible.   

 

 

Your state tax due cannot be paid from your federal refund. 

It is not possible to pay your state tax due from your federal refund, nor is it possible to pay a federal tax due from a state refund.  The federal and state treasuries are completely separate from each other.  You may have seen a TurboTax summary of your federal and state amounts that confused you into thinking one was “paying” the other.  It is not. The ONLY thing you can pay for from a federal refund is your TurboTax fees if you chose that option.  

 

 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.

No you cannot apply the federal tax refund to pay the state taxes owed.

In the File section of the program on Step 2 you will be given options on how to pay the state taxes owed.  Paying with the federal tax refund is Not one of those options.
