Foreign tax paid comes from Form 1099-INT box 6 or Form 1099-DIV box 7. If it's on a 1099-INT or 1099-DIV that you received, it's not an error. You paid the foreign tax, so you might as well take the credit for it, even if it's only $1.
If you want to remove it, or if it's not actually on your 1099-INT or 1099-DIV and was entered by mistake, go back to the screen where you entered the 1099-INT or 1099-DIV and delete the foreign tax from the appropriate box.
