the broker is supposed to adjust the basis of the shares causing the wash sale by the disallowed loss. in this case, you report exactly as shown on the 1099B because the disallowed loss should have been taken into a/c when you disposed of the shares causing the wash sale.
you should be able to recognize this on the 1099B because the cost of the wash sale shares should be = to what you paid + the disallowed loss.
if unsure contact Robinhood. they're the only ones that could answer for sure
