Things like direct deposits of refunds, direct debits of balances due, application of overpayments to estimated taxes, are computerized functions that should and used to work almost seamlessly. And if they still are, the computers that spit out letters are getting the wrong information. The DOGE kids had gotten into the IRS systems at one point. Could they have somehow messed up the coding? I can't imagine why electronic transactions and/or automated responses have become unreliable. I have seen a number of know-it-alls mess up their computers by rapidly clicking away without reading what is on the screen. If the kids inadvertently broke something, they surely know enough to fix it so hopefully these odd letters will cease soon.
