I've read various interpretations from sports betting and how they define sessions.
For example, if on one site (say DK) you had 10,000 in wagers, and 11,000 in wins, since it was from the same site, you can report the session (2020) as 1,000 in gross winnings, however, if you had a separate site (say FD) and had 1,000 in wagers and 900 in wins, you wouldn't take the net of both sites combined, instead you would do 1K in winnings, and for itemized deductions you can take the 100 in losses. Can this logic be applied?
Otherwise you are adding 11,900 of income to be taxed on, and unless you itemize, you wouldn't be able to write off any of the 11,000 you lost (wagered). So it would result in you being net positive 900 for the year, but having to pay taxes on quite a bit more income than that.
