I entered a 1099-B Stock sale that should be taxed at the Long Term Capital Gains Rate (15%). The sale is being taxed at 25%. How do I fix this?

The stocks were purchased more than a year ago. The 1099-B classifies it as "Long Term Noncovered" but does have a Cost Basis.

After reviewing the Tax details I found that I was subject to the Net Investment Income Tax (NIIT) because my Adjusted Gross Income exceeded the threshold. The NIIT was enacted in 2013 as part of the Affordable Health Care Act. It was intended to bring in some additional revenue. So that explains the higher than expected Tax Rate. Lesson: General Tax Advice is just that: General. It may not apply to your situation.

enter the correct dates.

Make sure you have Sales Category Box E assigned.

Those entries are correct. When I Zero-out the sale and cost amounts and take the delta-Tax Due amount divided by the Net Gain, I see a 25.00% tax rate Fed and 9.3% State. This doesn't seem right to me...

Why don't you simply answer your own question?  If you're really using a desktop version of TurboTax print out your income tax return "for filing" both before and after the LTCG is entered and pore over the two versions line by line.  You'll find out the reason which probably includes one or more of our tax code's "gotcha's".  Tell us what you find.
