Does Turbo Tax Provide a Standardized Table of the various Income source that needs to be included/removed from the AGI based on the various purposes of MAGI calculation; e.g. per FED Form (traditional IRA deductibility, ROTH IRA Contribution limits, additional ACA tax, etc.)

The two are similar, but have some slight differences. TurboTax will automatically calculate MAGI when it's needed for determination of a deduction or credit.
