Ok, at 19680lbs and otherwise the same parameters I got:
V = 523,9 km/h => 42,46 km/h less than at 9680lbs
T = D = 7653,63 N => 485,61 N more than at 9680lbs
Comparing the amount of induced drag at all these weights:
at 9680lbs Di is 382,45 N ie 5,34% of total drag
at 10280lbs Di is 433,60 N ie 6,04% of total drag
at 19680lbs Di is 1847,45 N ie 24,14% of total drag
