Get your taxes done using TurboTax

Please correct my number of IRMAA/MAGI

In TurboTax after entering all incomes TurboTax will list out all incomes and Total. Is this Total equal to IRMAA/ MGAI? I used Excel to list out all incomes it turns out very close to this TurboTax number. I believe My Excel Speadsheet was round off to be quick list.

Can someone shine the idea?
