When you moved/changed your address did you put in a 'change of address' with the post office. It is unlikely that your employer has mailed out W-2s --yet. It is still early (1/2/20). You can access the US Post Office website and enter a change of address request which should result in your mail being forwarded from our olr address to your new address.
That said, the best this to do is contact our employer and find out what they suggest.
