Amend, Unemployment and a missing W2

Hi everybody,

I have a question, and I hope somebody will have an answer for me, because I can't find it anywhere online.

I filed my taxes, got my return and everything but I forgot to add 1 W2 from my part time job. Also I received the unemployment in 2020, but I did my taxes before the American Rescue Plan was signed. How should I procced from here? Wait for the Unemployment difference to be deposited back to my account and them amend with the missing W2? 

 

Thanks
