    TurboTax "Federal Refund" ignores "Self-Employment Tax"

I did my taxes manually and then came to TurboTax to double check. It calculates a larger refund than I do. The strange thing is that the refund amount is off by exactly the amount of the self-employment tax, in my case $374. This amount shows up correctly when I look at the section specifically about the self-employment tax, but the federal refund amount ignores it.

Is there some way that TurboTax figured out to appropriately avoid paying the self-employment tax, or is it a bug in the software?
