RMD on Cash Balance Pension

I will be 72 this year (2022), so am subject to RMDs.  In March, I rolled my cash balance pension plan into a traditional IRA.  My understanding is that the plan administrators should have excluded the RMD from the IRA roll-over and instead distributed it outside of the IRA.  This was not done.  I called the plan and asked them to either provide the amount of the RMD or the account balance as of Dec. 31, 2021 so I can determine the RMD.  However, they tell me no RMD is required and have not provided the Dec. 31 balance.  I have asked them to state this in writing.   Do I need to take and RMD and how should I determine the amount?
