" So now, there is no way for the brokerage account to correct it - either re-characterization to traditional or a corrective distribution. Because the money doesn't exist."
That's false. You still have money in a Roth IRA, so you still have a $1,500 excess Roth IRA contribution for 2022 that is subject to penalty unless you take the position that the regular distribution you made qualifies as a return of contribution as I described in the last paragraph of my original reply. Absent doing that, avoiding the excess-contribution penalty still requires correction, either by recharacterization or by a proper return of contribution.
Are your converted funds in the same Roth IRA account as the one to which you made the deposit of the excess contribution?
In what year did you do your first Roth conversion? Was it a taxable conversion?
