When I enter my business expenses in each category, the total sum shows less than actual sum, which resulted in higher net income. How can I correct it? Thanks

Some categories of business expenses have limits on deductibility.  For instance meals deductibility is limited to  50% of the total.

Thanks for the answer. However my situation seems different. I think the net income is set to 10% of the income. I tested by increasing some of categories but the net income stayed the same. I added up all the number in the itemized section but when I come back to the business summary page, the "Other Common business Expenses" did not change. When I reduce some numbers, the expense number reduced as well. Is there any limit on the deductible expense?
