Variance in net income

Hello,

 

My spreadsheets show $11,000 net income on a flip house that we did but Turbo Tax says the income is $14,000.  I triple checked all of my numbers and they are accurate.  I have input them them into Turbo Tax accurately as well.  I don't want to pay extra taxes on money we didn't make.   Can someone please suggest what could be causing this variance?   

 

Thank you!

Linda
