I'm super confused about this MAGI calculation, specifically concerning SS payments. In your response you indicate to calculate MAGI you would take AGI plus the non-taxable portion of SS payments (assume no other adjustments). I've seen some other articles online that say the same thing. Others that don't mention SS at all.
I've completed my 2020 tax return using Turbo Tax Premier. Due to other pension income, interest, etc., part of my social security is taxable. When I pull up the MAGI worksheet the figure it is showing actually excludes the taxable portion of my SS benefits. So my MAGI is less than AGI by that figure. Shouldn't the MAGI figure be higher by the non-taxable portion? Is this schedule wrong in TT?
