mailing state is free while TT charges to efile state. (except New York)
if TT won't allow you to submit state return there is either a critical problem with the data you entered or a form you need hasn't been approved by the state. you can mail payment with the return, however, I'll bet you can pay electronically through your state's website. the state may even allow you to specify a future date when payment will be processed - even as late as 4/15 or the initial due date of the return. there will be no charge if the payment comes out of your checking or savings a/c. there will probably be a fee if the state allows payment using a debit or credit card.
