You are not supposed to "scale" QD/CG backwards to previous periods. Line 1 (a) - (d) is for AGI actually earned in each period. Example Line 1(a): $20,000 wages - $1500 pre-tax health insurance premium - $2,000 401(k) contribution + $2,000 QD + $2,000 CG results in $20,500 for Line 1(a). Line 13(a) = $20,500x4 - $12,550 = $69,450. Tax Table lookup: $69,450 - $2,000x4 - $2,000 = $59,450. QD/CG tax = 15% x ($2,000x4 + $2,000).
