After you file

You may be able to carryover your unused foreign tax credits from previous years to the current year. You will see an option for this in the Estimates and Other Tax Paid section, then Foreign Taxes, which are in the Deductions and Credits section of TurboTax. When you work through that section, indicate that you want the foreign tax credit as opposed to the foreign tax deduction. After you enter your foreign income received in the current year and answer other questions, you will come to a screen where you can enter your foreign tax credit carryovers. You can only receive a foreign tax credit to the extent you have income tax on foreign income in the current year.
