Ok ... let me tell you a secret ... you don't have to enter any of those individual W-2G forms in the program at all. The IRS doesn't get or need all those entries ... all it gets is one amount on the form 1040 line 21. Entering them all individually would be for your use/records only so if you don't want to enter them all you don't have to.
Skip the W-2g entry screen and just enter the total winnings on this screen ...
