A 20-pound to 24-pound turkey will thaw in the fridge in 5 to 6 days.
Therefore, it would take 5 days for a 20-pound turkey to thaw in the refrigerator, and 6 days for a 24-pound turkey to thaw in the refrigerator.
_____________________________
It would take a 20 to 24-pound turkey 10 to12 hours to thaw in cold water.
***If you are thawing in cold water, it is very important to change the water every 30 minutes.
