How do I know the total I owe? I printed out my forms to pay the taxes, it says an amount for state and different for federal. But on the app, it shows I only owe for federal not state. Help

If you indicated in the FILE tab  that you will mail in the returns  then look at the filing instructions for both the fed & state returns ... it will tell you everything you need to know. 

At the end Turbo Tax shows you the net federal and state combined.  But you need to pay each tax due separately.  Or if you are getting a refund on one you can not have a tax due on the other one deducted from it.  You still have to pay the full tax due yourself.
