I have a brokerage account with stocks from an ETF in two different countries, and I paid $4 in foreign taxes on the dividends. While I was figuring out whether to claim it as a foreign tax credit or not, I accidentally listed it as an itemized deduction, which added $4 to the amount due in federal taxes, and I am having trouble changing it back. Is there a way to undo it, and what are the steps in claiming it as a foreign tax credit?
