I don't think TT is calculating the MAGI on line 1 of this worksheet correctly.
The MAGI (for Roth contribution purposes) should subtract both IRA to Roth Conversions and 401(k) to Roth Conversions from the AGI. I had substantial Roth conversions in 2025 that should have reduced my Roth MAGI below the $246k joint threshold. These Roth Conversions show up on line 4b and line 5b on Form 1040. However, the MAGI on line 1 of the ROTH IRA Contribution Limit Worksheet only reduces the AGI by the amount of the IRA conversion. It does not seem to subtract the 401(k) conversion that increases my AGI on Form 1040 line 5b.
Thanks for your help on this.
