Amend tax return 2019

Hello, i e-filed my taxes on 15 April 2020 and i haven't receive my federal refund yet. After the e-file i noticed that the W2 has the worng SSN. I conctacted my employer and they sent me a W2-c

 

Since a long time has passed and nothing has happened, should I complete an amend tax return ? 

If i amend a tax return, is there a probelm with the state refund? ( I want to mention that i have received state refund. )

 

Thank you
