I filed my taxes on the 22nd of January. They were accepted by the IRS on the 1st of Feb. Feb 5th, the status changed back to pending. Last Saturday, I got a letter 12c from the IRS stating that i hadn't filled out a form regarding estimated tax payments. I didn't make any estimated tax payments, nor was I required to. I called them and was told the letter was probably sent by mistake and to fax it back, along with a note telling them that I didn't make any estimated tax payments. I did that a few days ago and was wondering if anyone knew how long it would take to hear back from them. I'm kind of worried we're going to get audited or something and the people I get ahold of when I call don't seem to know anything. They just keep saying there's nothing in my file that would have caused the letter to get sent in the first place. I'm getting so frustrated!!!!
