Then yes, before the rest was rolled over to the IRA in 2022, there should have been the 2022 RMD paid to you from the plan based on the 2021 year-end value of your interest in the plan. The RMD amount that was inadvertently deposited into the IRA constitutes a regular contribution to the IRA rather than a rollover and, if you have no compensation to support such a regular contribution, that entire amount constitutes an excess contribution to the IRA that needs to be distributed by an explicit return of contribution before the due date of your 2022 tax return, not by a regular distribution. The amount distributed will be the amount returned adjusted for investment gain or loss. If there is a gain, the gain will be taxable on your 2022 tax return.
If the plan issues a code-G 2022 Form 1099-R showing the enter amount moved to the IRA instead of a code-G Form 1099-R showing only the permissible amount of the rollover and a separate code-7 Form 1099-R for the RMD amount and any tax withholding and refuses to make the correction, you'll need to submit substitute Forms 1099-R (Forms 4852) with your 2022 tax return to correct the reporting.
