"the return you people helped me file"
This is a user community forum--not a direct route to the folks at TurboTax Support, so we people don't know what product you used. By "helped" do you mean you used a TurboTax LIVE product, for instance, which has live help on-demand from a tax expert during return preparation and a review of the return prior to filing? If so, the Audit Support Center should be able to help you connect to a tax expert.
