I want to claim gambling losses on my return. With online casinos, is a win/loss statement enough for IRS documentation, or do I need a log of thousands of events?

I played at multiple online casinos this past year. I have tried to get a detailed log of all events connected to my account over 2021, but all I keep getting is a win/loss statement. Since it is ALL online, they must have record of it somewhere.

A document showing your total loss for the year would be acceptable to the IRS.

That is great news. I was having trouble getting my hands on the detailed log. I figured that since it was all online, it was verifiable. Thanks.
