On Misc investment income screen, it is auto checking the "foreign account" box everytime I go to the review step.

To clarify, do you have a 1099 INT or 1099 DIV on a consolidated Brokerage statement.  If so, check to see if there is a foreign tax paid in Box 6 of the 1099 INT or Box 7 of the 1099 DIV.  If so, then there were foreign interest or dividends paid and you need this information to determine the amount of foreign credit to claim on your return. If this doesn't apply,  try this.
