There is no option to have TurboTax print and mail your returns for you. You must do that yourself because your return must be signed by you. You apparently misundertood what TurboTax does.
The only way to contact TurboTax by phone is to set up a call back: https://ttlc.intuit.com/community/using-turbotax/help/what-is-the-turbotax-phone-number/00/25632
