My income includes employment, rental and dividend income (non-eligible). It appears that Turbo tax applied the tax rate for employment income to the dividends.

When you add dividends to your Total Income on Line 150 of the tax return. They are taxed at the same rate as all other income, but you receive a "dividend tax credit" to offset this.

The dividend tax credit is not included in the Detailed Tax Summary, so I thought it was missed.
