After you file

I filed also on the 28th and was accepted on the 28th. And went to approved to take action within a week. I called and was told it was in review. Until today. Called yesterday and said a letter was sent on 21st saying no action needed just that they were waiting on w2 from employer but their mail is back logged so just waiting on them to enter it. Now it’s processing. So it shouldn’t be much longer
