On schedule 1A, which calculates the amount you qualify for the additional senior $12K when both parties are over 65 and filing married filing jointly, it appears the final calculation is based on the individual $6k x 2 vs the $12K. All dollar amounts that turbo tax uses in the schedule 1A are fro MFJ, but once the phasing calculations are completed, the calculations are subtracted from $6K vs. $12K
As an example, MAGI is $226k for 2 seniors over 65. Since this amount is over $150K by $76K x .06 phase out calculations is $4560. I believe the phased out amount should be subtracted from the $12k max, reducing the the overall senior deduction to $7440. HOWEVER, Turbo Tax takes the phased amount $4560 from $6k (the per person amount) or $1440 then multiplies x 2 for total deduction of $2880. The difference in these calculations is $4560 less. Anybody agree or is TT correct?
