Q:

What is the て-form of みます? 

I have learned from my previous studies that it is みんで.
However, Google translate seems to give me the answer みて.
Which is correct? 

A:

If you are talking about [見]{み}ます/見る, the て-form is 見て。 

A:

If OP really wanted to make a distinction between みる and みます, then the te-forms would be:

みる　⇒　みて
みます　⇒　みまして
