In general, if your original return was electronically filed using TurboTax, then your amended return may be electronically filed.
If it is electronically filed, then there is no need to mail a hard copy to either the IRS or the state. As you are finishing up the amended return, just make note of whether you are choosing to file the amended return electronically or by mail. If mail is selected, then TurboTax will print an instruction sheet for you so that you know what you need to mail and where to send it.
