Retirement tax questions

I called the administrator/trustee and they said that the conversion will be effective for 2022 not 2021 . A 1099 will be issued for 2022.  They claim this is because they need at least 5 days prior to end of year for processing.  There was no notice on the web site about the 5 days needed and my statement and web account shows the conversion was completed 2021.

 

Do I have any recourse ?  Does the IRS use the 1099 as the date for the conversion or my statement  ?
