After you file

I also have an as of date of 4/27 on my transcripts. I file 2/2, accepted same day. My processing date is 3/9. Called early March after not receiving anything and they said I was under a 45 day review. They said if I didn't receive my return by 4/24 to call again.....which now we know that will do no good, since they are closed right now. My next move is to contact a tax advocate in hopes to get my return off hold. I honestly do not understand what the as of date means....my only guess is that is when my account would start to earn interest that they would then owe me as well.
