This shouldn't be any problem for you. The RSU income and the taxes covered by the sale are already lumped into your W-2 and should not be reported separately.
The only remaining thing for you to do is to report two same-day sales that have a cost equal to the RSU market value on the date of exercise and a sales price as listed on your account paperwork, typically the same as your cost. You will end up in most cases with a small short-term loss to report because of commissions paid as part of the sale.
