Support is closed for the weekend. Did you purchase Audit defense for that year?
That's a lot. Did you leave off some income? What did they change?
If you purchased Audit Defense for your tax
return, call Tax Resources, Inc. at (877)-829-9695, or report your notice on their web site at http://intuit.taxaudit.com/. Do not contact the
IRS. Let Tax Resources contact them for you.

If you
did not purchase Audit Defense:
TurboTax has a special phone number for help with IRS
tax letters, which will be easier than going through regular Customer
Support. At the page below, click on the blue button that says
"Get Help from TurboTax Support". Then it will ask you
what tax year is your letter. Then it will ask you what the letter
concerns. Then it will show you the phone number during posted business hours.
