You can enter the foreign pension income on Form 1040, Line 21 as "other income" or "foreign pension."
To report your foreign pension in TurboTax follow these steps:
- Log in to your TurboTax account if it is not open.
- Select the Wages & Income tab.
- Scroll down to Less common income click Show more.
- On the page Let's Work on Any Miscellaneous Income click on Other reportable income.
- On the page Any Other Taxable Income? select yes.
- On the page, Other Taxable Income enter Foreign Pension for the description and the amount.
- Select continue and answer No on the next page.
