Go to the state section titled Taxes and Credits and look for the Out-of-State Credit question. Answer Yes and a screen will display allowing you to select the foreign country (click on Other Countries if more than one). Click on continue.
The next screen titled "Double Taxed Income" allows you to enter the gross income and tax amount paid to the foreign country. This entry may be made for taxpayer and/or spouse if filing separately on a joint return.
TurboTax will create the required IA 130 form with the answers you enter.
