Prizes and Gambling are two seperate lines on schedule 1..

Line 8b then.

Is there any problem reporting a 1099 on gambling? I wasn’t sure if the AUR would not be able to match because it typically wouldn’t look for A 1099 on that line

There should not be but even if there is, the transaction should be reported appropriately.

If there is a mismatch, and a letter is generated, that would easily be dealt with by a response showing the income was from gambling.
