Client went on an online gambling binge.  Has nearly $365,000 in winnings.  He provided confirmation that his losses exceed his winnings. He has a full time job besides his online addiction so he is not a professional (in his mind he may be) Gambling problem?  Who am I to judge. 

Anyway, please confirm my understanding that there is no need for me to enter all 64 W2-G's individually.  I summarized the amounts in the spreadsheet and just plan to enter one W2-G with the total amount of the winnings using 12/31/2023 as the date.  I'll show the total losses (up to total winnings) on Schedule A.  I assume adding the spreadsheet as a pdf is useless?
