Sale of a second home just goes under Investment Income. You would use the first category, stocks, bonds, mutual funds funds and Other. Gains on the sale of a second home are taxable but losses are not deductible. If you entered it under Sale of Home you need to delete that, along with foreign tax information. That's for a primary residence.
Go through the foreign income interview by entering the words foreign income in the Find window on the upper right, hit enter, then the Jump To that appears.
