To my eyes this plant’s flowers & branching habit look similar to the American Burnweed (Erechtites hieraciifolius). The flower of wild lettuce (Lattuca canadiensis) has yellow color and no branching at the lower portion of main stalk. Copy & paste the included link below and check out the identification keys for this species. Best wishes!
For future reference please show the plant in situ, side view, and closeup of flowers, fruits & seeds. These clues would help us quickly narrow down its ID for you.
