Should a retail financial advisor firm give me foreign tax credit information?

I invested in an Irish ‘offshore’ fund through this firm. The fund invest in assets all over the world but 50% is US equities. I am not an US person.
I read offshore funds gets tax withholdings for about 15/30% of the US dividends.
I have the chance to present foreign taxes for my home country tax credits.
The advisor says the fund reinvest dividends and that I wasn’t withheld anything.
(But I guess the fund was withheld)

What should I do/ask?

Thank you!!
