RMD

In doing 2024 taxes I recieved a distributoion from my IRA.  Per the IRA holder my RMD for the year was 8967 which I entered.  I took a total distribution of $12,000 (1,000/mo).  Turbo Tax said I owed an additionmal $2285 in taxes for my RMD.  When I went back to the form question on RMD and entered the full distribution of $12,00 this additioanl tax requiement went away.  I also have a pension which I belief does require an RMD.  Wht did Turbo Tax say I owe additional RMD above what my hIRA Holder says is required?
