That particular field between lines 10a and 10b is just a worksheet number, (I'm not sure exactly what/how that -particular "worksheet" field works . ) It doesn't really show on the actual form 1040
But if you look down , lower.............the 50k you entered then actually shows up as a deduction on line 12 of your form 1040.....that comes from your total itemized deductions on the Schedule A
