@kkmrhktax , this thread has nothing to do with your circumstances if you have not received any distributions from an inherited IRA and involves an MAGI that is erroneously calculated too low, not too high.
If, when calculating your MAGI, your AGI is not being reduced by the taxable amount of your Roth conversion, you've likely entered the Roth conversion incorrectly. When entering the Form 1099-R that reports the distribution from the rollover IRA, make sure that you have indicated that you moved the money to another retirement account and either have indicated that you converted to Roth (online TurboTax) or you did a combination of rolling over, converting and cashing out (CD/download version of TurboTax) and have indicated the amount converted to Roth. Confirm that you have reported the Roth conversion correctly by reviewing Form 8606 Part II to see the taxable amount of the Roth conversion.
