Prepare the thermometer before checking turkey
Read the model instructions, clean the probe, and confirm that the display is working. If accuracy is in doubt, follow the maker's calibration or accuracy-check procedure before relying on it.

Guide
Check the thickest part of the breast plus the innermost thigh and wing. Keep the sensing tip off bone and verify every required location before serving.

USDA guidance calls for checks in the thickest part of the breast and the innermost part of the thigh and wing. These separate readings matter because a whole bird does not heat evenly.
Push the sensing area into the center of the thickest meat from a stable angle. Bone and the roasting pan can conduct heat differently and give a reading that does not represent the surrounding meat.
Do not stop after one favorable number. Measure the breast, inner thigh, and inner wing, allowing the reading to stabilize according to the thermometer instructions each time.
USDA lists a safe minimum internal temperature of 165°F for turkey, measured in the specified locations. Stuffing, whether cooked inside or separately, should also reach 165°F.
Resting can allow temperatures to shift, but it does not replace reaching the safe endpoint. If one area was close or difficult to measure, recheck it before carving.
Common questions
Insert far enough that the thermometer's sensing area reaches the center of the thickest meat. The required depth varies by probe, so check its manual.
Avoid bone because it can produce a reading that does not represent the meat around it. Reposition the probe into the center of the flesh.
Check both, and also the innermost wing area. USDA guidance identifies all three locations for a whole turkey.
USDA states that the center of the stuffing should reach 165°F, whether it is cooked in the bird or separately.
