Retirement tax questions

Does this picture help?

My actual Grossl income for the S-Corp is $140,165

Why is there a line that has a total of $282,560?

 - $282,560 = 2x $140165 + $2,230 and there no combination of numbers I can find that = $2,230

Is it an error in the form (last year that "Total" line did not exist)?

If it is correct, where does this number come from?
