Business expense way understated in summary

[vikingcat]

My and my spouse's schedule c expense detail total close to $13K each. But the Business Summary form shows expenses totaling $5712 for each of us. Huh? The latest update is installed, I closed and reopened TT and finally closed and restarted the computer. Nothing changed. 

This is an unusable product if it can't add numbers and transfer them to another sheet. And it is the end of February, it should be right by now, calculation-wise.

I've been using these products since the Mac-In-Tax days. I've never dealt with a "can't add" problem before.

Help.

Look at Schedule C.  Are all the expenses listed?

Some expenses, such as home office or section 179 depreciation can only be used to reduce your schedule C taxable income to zero, and not to create a loss. Excess deductions for these carry over to the next year.  And you have to answer yes to both questions about exclusive and regular use, not just one.  The area of your home office must be used regularly and exclusively for business to deduct it.

Or you checked the box on 32b saying Some Investment is Not at Risk.

If you have money not at risk you can not take a loss on schedule C. If you don't know what it means then probably All your Investment is at Risk (check Box 32a). It means you are using your own money for the business.  People usually check the wrong box.
