You likely put something to the wrong place and/or didn't enter something at all. That's about the only way you can be "out of balance."

Can you give us your data, as examples? For instance, this: "this taxpayer bought and wrote off a 6000 vehicle"

Is often entered incorrectly as the purchase going directly to Expense. Then, the depreciation is also going to expense. Or, the Loan payments were posted to Asset value, and there never was the debt entered. These are common mistakes.
