Thanks for responding, Florida. Be prepared to “wait” on the phone. I was “in line” we will answer your call in 30 minutes – sure after well over an hr. they finally answered that they got the fax – but hadn’t done anything – nor would they be able to answer anything. There ya go. It’s now 2 months. I am tempted to “write (letter)” yes the fax was sent & IRS “said” it was there, but does interest keep going – if I did make an error? I really have no idea.
