You can skip all the W-2G entries completely and simply enter the total winnings and the total losses. Just skip the W-2G entry screens by saying NO you did not get those forms. If you had withholding on any of those forms then you will have to enter those forms however you can combine slips from the same issuer without a problem ... remember the IRS got the original forms from the issuer so they don't need you to enter them all on the tax return ... all they need from you is the total winnings on the return.
