If you purchased Audit Defense from TurboTax before the tax return was filed then go to intuit.taxaudit.com and select Member Login (upper-right corner) or call (877) 829-9695 toll-free.
If you did not purchase Audit Defense then you can use the TurboTax Audit Support Center where you can get assistance in understanding the IRS notice you received and get steps on how to proceed. The Audit Support Center does NOT represent you before the IRS or contact the IRS on your behalf.
The Audit Support Center is open from 5am to 5pm Pacific time, Monday thru Friday.
Go to this TurboTax website for the Audit Support Center - https://support.turbotax.intuit.com/irs-notice/audit-support/
