I’d budget around 30-45 mins. Lots of variables at play that impact being more precise or any advice being 100% reliable.... monorail delays on either the Resort or Epcot line (since you need both), security lines at both CR and then again entering Epcot (the Epcot security line can be stout at times), holding for further monorail traffic clearance, etc, etc.
If you have something very time sensitive awaiting you at Epcot, I’d budget an hour just to be safe.
