Tax return incomplete

I file my last tax return with Turbo Tax and I just received a letter from IRS saying that my return is incomplete. They ask me for schedule which is for self employed when I am just a employee in a big company.

Working and living in France makes it difficult to communicate with IRS or Turbo Tax; I don't know what to do to fix this mistake. I couldn't find a way to speak with anyone at Turbo Tax.

I must say that for a first time filing with Turbo Tax I am very disappointed.

Thank you for your help.
