My clients (husband and wife) received over 200 W-2G's. None of them have any federal or state withholding. Do these need to be entered individually or can they be summarized in some way? (Like by the casino.)  This is what the IRS Interactive Tax Assistant says: "You must attach to your return copies of any Form W2-Gs received." (For e-filed returns I assume this would mean they should be entered into the W-2G worksheets which have no limit to the number entered in ProSeries Professional.)
