IRA distribution

I got a the minimum distribution from an inherited IRA of $1,200.  Eventhough we are in the 22% bracket, this is being taxed at 27%.  Not sure why that is.  Before adding this distribution we were due to receive $220 return, after inputting this distribution we owe $104 in taxes.

This $1,200 does not put us in a higher bracket.

Why is this being taxed at a higher rate?

Thank you,
