It has to come from a Traditional IRA.  If this was a prior year, correct it ASAP and use Form 5329 Part IX to request a waiver of the 50% penalty (in my experience these are basically automatic, every one I've done has disappeared into a black hole, never to be heard from again.)

From page 7 column 3 (2021):

"If you have more than one IRA, you can
take the minimum required distribution
from any one or more of the IRAs (other
than Roth IRAs)."

Page 8 describes the waiver process under "Waiver of tax for reasonable cause."
