I had filed my 2018 fed and state taxes with you guys. When i filed my fed taxes i thought that i used my fed return to pay my state taxes. is there a way to confirm this

There is no way to use your federal refund to pay your state taxes so nothing needs to be confirmed because it can't be done.

Pay your state tax due by mailing a check or money order, or by going to the state’s tax web site. It is impossible to pay a state tax due from your federal refund—you misunderstood.
