Why this is taxed at 9,000 USD?

I file my taxes jointly. I'm the only one with a W2.

I did my W2 and I have a credit of 660

After I downloaded my stock activity that consists of:

Long term sales with cost basis reported to IRS of 92,252.77

and 

Short term sales with cost basis reported to IRS of -8393.82

I have a federal tax due of 8840.

 

From what I've read the Long term capital gains are taxed at 0 for first 80K and 15% thereafter.

Short term there is no gain so I'm not sure how turbotax came up with 9000 taxes. Any help will be appreciated.

 

Thank you,

Chris
