What costs are on your spreadsheet that either TurboTax did not ask for, or you did not enter?
Now my screen shows you're using TurboTax Business which is only available as a Windows program that you install on your windows computer. So that means you can click the Forms Mode button in the upper right of your screen to see the forms and calculation worksheets. So do that, and just "follow the numbers".
Don't know if it matters or not for your specific and explicit situation, but I might help to know if you're completing a 1065 partnership return or an 1120 or 1120-S corporate return.
