@JamesVDale - can you please go back and review your post and your data entry one more time (may be worth someone else checking the data entry as well)
1) Dividend Income should appear on 7
2) US Government interest is a form of interest and should appear on Line 6 (you state Line 7)
3) please go back and re-confirm that when you entered the Interest and Dividends you indeed clicked who owned the income - husband or wife - correctly..... if "joint" is clicked, then the income will be split 50/50.
