On the left hand side of the screen, go to "Tax Tools" then "Tools," then "View Tax Summary." Delete the expenses and record the breakdown of the tax summary. Enter it in again and look at tax summary to see the difference. I would imagine the difference is the credits you received by earning more money. From there go to "deductions and credits" to see which credit was reduced. Either way, the IRS requires the taxpayer to include all expenses on their tax return.
