IRS accepted my TT return electronically 01/30 (same day I filed) got to first bar only on WMR then it turned to code 9001 a few days later. I called they said they sent a letter out 01/31 and I have to wait on it. That was a lie. My letter finally got here Mar2 (Saturday) gathered my paperwork and have spent two days calling about 9 times per day CANNOT GET THROUGH!!! DID anyone else have this problem? Is there another way to get them by phone. I'm calling the number on the letter....
