Qualified dividends are already included in the total ordinary dividends reported in Box 1a of Form 1099-DIV and are separately listed in Box 1b. So, if your Form 1099-DIV from the life insurance company lists both, you don't need to report the $250 qualified dividend separately as an ordinary dividend.
Enter the numbers exactly as shown in Box 1a and Box 1b and TurboTax will ensure they are entered correctly on your tax forms.
For more details, you can check out the IRS instructions for Form 1099-DIV and TurboTax explanation of qualified and ordinary dividends.
