After you file

I just talked to an advocate that said nothing wrong with my return it is still just processing because of the credits I am receiving.  She said to check tomorrow after 3pm and give it a week before I call back or be concerned.  Nothing about a letter or extended review process or identity.  She said they are reviewing more returns for people who owe money to be sure they are not trying to get out of paying the whole amount they owe.  More people lie about that than refund. So she said.... I am trying to be patient....
