Foreign Pension is taxable in the US. You will enter it as if you received a 1099-R, even though you will not receive such a form from foreign countries. Even your lumpsum payment needs to be entered as a 1099-R income. As you have not paid any takes in Netherlands for this income, you will not get a foreign tax credit on them in the US. Had you paid taxes on this in the foreign country, you would claim a tax credit based on the tax treaty to avoid double taxation on the same income by reporting the foreign taxes paid in the Foreign tax credit section. To make the entry in turbo Tax, to report the pension, in Federal section, you would go to Wages and Income, then select Retirement Income and make the entry from there. Remember this income maybe subject to state taxes as well depending on your state of residency.
