If you have glued it together correctly then best fix is --- Get abottle of ammonia & cut some with 50% water , to cut down smell . , ok soak some on the wing /airframe,use paper towel is best , then pack the wing up solid with packing . clamps etc . When you clamp it , GO PAST the point where you want it square , as it will come back still with the twist you mention if you don't , so leave it weighted down overnite & take clamps off in morning . If ok , & it is a flimsy wing , cover carefully after it is true as soon as possible . Good luck
