Ground turkey and even a whole turkey once thawed can be microwaved if your microwave is big enough and has enough power.
If you have a regular oven though to cook the whole turkey the turkey turns out better in the oven then in a microwave.
If you have raw ground turkey you can also microwave it and it will cook to be safe to eat although I would recommend cooking the raw brown turkey in a pan instead of the microwave.
I tried microwaving raw ground turkey before and it did cook just fine but it was not as tasty as it would be if I had cooked the raw ground turkey in a pan.
The pan and some cooking oil cooks and browns the ground turkey much better.
