TurboTax Capital Losses Calculation Doesn't Match 1099-B

I have only one 1099-B, and it was imported from my brokerage.  The 1099-B has a $67.83 total short-term capital gain and a $1,551.51 total long-term capital loss, which correctly shows as a $1,483.68 total loss in TurboTax on the investment income page.  However, on the "Here's a breakdown of your capital losses" page, TurboTax comes up with $1,448 in total losses using a short-term capital gain of $68 and a long-term capital loss of $1,516.  The "explain why" wasn't helpful since it doesn't show where the software is getting the values.

 

How/where is TurboTax getting the $1,516 loss?  Why doesn't it match the 1099-B values?  I've looked at the forms and can't figure out what's wrong.  How do I fix this?
