You can take a foreign tax credit or deduction on your US tax return.
If your dividends are on a 1099-DIV or another US tax form, enter that form in your return before you start the Foreign Tax Credit section.
If all of your foreign tax is on your 1099-DIV and your foreign tax is $300 or less ($600, if married filing jointly), you may not need to file Form 1116.

The foreign tax may qualify for a foreign tax credit since it is based on income. However, you can only use the foreign tax credit to the extent you pay US tax on the foreign income. So, unless you have other foreign income on your tax return, the foreign tax credit would be suspended until a year when you had foreign income that was taxable on your US tax return. The IRA income would not be taxable until you took a distribution.
