After you file

petergabp:
As I said above this is an old thread from last year that has long been moved to the answered queue.   If you want, start a thread on your issue so it will show up to the whole forum as needing help.  You may get additional comments, and you might hear from folks who had the 4464C letter.  Be sure to mention the letter number in the question title.

You can start your new thread at the link below so it will show up to the whole forum:
<a rel="nofollow" target="_blank" href="https://ttlc.intuit.com/questions/new">https://ttlc.intuit.com/questions/new</a>

When you go to the form at the link, the first box is for a summary of your question, like a title, and is limited to 170 characters..  If you need more room, lower on the form you will come to another box with plenty of room to enter details.  This is a public Internet forum, so don't post any personal info.
