Deductions & credits

This stuff is crazy. No updates to transcript as of yet, no ddd either, and haven’t received any correspondence. I have tried multiple times to call the irs but am unable to get through because their phone lines are too busy & call back at another time. I just need some clarification & direction. I am following a refund group on fb. Someone else with the exact same codes as me 810,811,917, and 420 got their correspondence in the mail for audit for the eitc & ctc. Basically saying for each dependent you have to send in proof that you can claim that child & proof that the child is yours or related to you (birth certificates), school registration papers matching that kid to your address or medical records or court documents. On top of that, they have to send in proof of house hold status to get head of household like mortgage, deed, rental agreement… so on so fourth. If you can’t prove your kids attachment to your address with you on it, then you have to send in separate proof that has your name on that address, like an electric bill or something. Although I haven’t received my “notice” yet, I’m preparing my documents now & sending them in this weekend or more preferably tomorrow, if I can get everything together. I don’t have the fax number yet, but I will post a copy of the letter my friend sent to me, so anyone else can prepare accordingly as well! Good luck everyone & well wishes!!
