I don't understand what you mean by "the option to file as living abroad." There is no such option on a tax return. What exactly is it that you can't find in TurboTax?
When TurboTax asks for your state of residence, select "Foreign or U.S. Territory" from the drop-down list. When it asks for your mailing address, select "Foreign Address" and enter your foreign address. There are topics in the TurboTax interview for the foreign earned income exclusion and the foreign tax credit.
