Social Security Benefits verses Taxable Income

Hello.  TurboTax says that my Taxable income amount (6a) is about $60,000 less than the Social Security benefits that my wife and I received.  We file jointly.

That seems like a big difference, to me. 

TurboTax has checked and double checked everything and says we are ready to file, though.

 

Should I be worried?

Thank you.
