Deductions & credits

All I know is a notice was supposedly sent on 02/04/22 according to the irs phone rep I spoke to however Notice sent stated the date 2/21/22 . I was told the notice is basically stating they want me to prove my eic is correct which I have everything will want if that is truly what the letter is stating so I’m trying not to freak out till this letter gets here but I can’t wait a year or even months I need this money now and tax advocates are taking about 2 weeks:(
