After you file

PAY WITH RETURN. means exactly that. you need to pay your income taxes based on the instruction that Turbotax provides. that may be sending in your check with a voucher, some states now allow you to pay electronically through their website. for other states, you can specify direct debit (just like federal) but then you have to provide the correct account and routing numbers. Turbotax never pays the taxes. that's your responsibility.
