@RobertB4444 Thanks, I guess that's what I'll do even though I know it's not correct--if it was everyone could just use option spreads on the last trading day to realize an arbitrary loss in the current year and a corresponding gain in the next year (hence the rule to realize gains on shorts on the trade date but losses on shorts on the settlement date, etc., to prevent exactly this).
I had enough losses in 2022, though, that it doesn't actually change what I owe in 2022 either way, though I may have to pay a bit extra in 2023 since the gains are now in 2023 without the offsetting loss, though not enough extra to worry about. I can't see the IRS getting too upset if I both followed my broker's 1099-B *and* doing so did not reduce my taxes.
