No, there isn't a standardized table provided by TurboTax. As you mentioned, the calculation of MAGI is different depending on the deduction. For example, to deduct a traditional IRA requires a MAGI calculation where the following are added to AGI (adjusted gross income):
- The IRA deduction itself
- Student loan interest deduction
- Foreign earned income exclusion and housing deduction
- Excludable savings bond interest
For a Roth IRA deduction, the MAGI includes the following add ons to the AGI:
- Student loan interest
- 1/2 of Self employment tax paid
- Deductible IRA contributions (not Roth)
- Foreign earned income exclusion and housing deduction
- Excluded savings bond interest
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.
For a more in-depth treatment of MAGI please see What is Modified Gross Income and How Is It Calculated?
