Newlyweds - Traditional IRA no longer deductible? Turbotax miscalculates my MAGI?

My spouse is covered by a retirement plan (401K) at her workplace but I am not. I should be able to fully deduct my $6500 Traditional IRA deduction, but Turbotax says none of it is. My MAGI is well under $218,000.

 

When I check the forms, in the IRA (Deduction) Worksheet, I see in Line 12 Turbotax calculated my MAGI as my W2 plus my wife's W2 (plus other misc. income too small to make a difference). Is that right?? Why would my MAGI include my wife's W2 for the purposes of checking if my Traditional IRA contribution is deductible?
