If you are using the TurboTax 2016 desktop editions the software would have informed that e-filing was closed if you tried to e-file after October 16, 2017.
If your credit card was charged for e-filing state tax returns and you were unable to e-file then you will need to contact TurboTax support for a refund.
Use this website to contact TurboTax support during business hours - https://support.turbotax.intuit.com/contact/
Use the key words billing issues when entering your problem and do not use the word refund.
