I put in a business expense but my "federal tax due" rose

[Patrice]

Whenever you enter your business expenses this reduces your taxable income and certain refund credits are based on the amount of taxable income that you have (for example: earned income credit and child tax credit).  Therefore by putting in deductions such as business expenses you are reducing your taxable income this results in a reduced credit and that results in your refund going down and your tax liability going up.
