No one can call you from the user forum. And for your own protection your phone number was removed by the filter from this very public website where it can be seen by anyone including scammers and would-be identity thieves who would love to contact you and pretend to be from TurboTax.
No, there are no "training" materials for using TurboTax. TurboTax provides software for a self-prepared tax return and if you go slowly and carefully through the interview screens, you can prepare your own tax return, letting the software follow all of the tax laws, do the calculations, and put the information on the forms, schedules and worksheets.
You can choose to upgrade to one of the "Live" versions so that you get help from a tax expert, or you can ask questions and get some help here in this user forum. We cannot see your tax return or your information.
If you need customer support:
Phone support is not provided with the Free Edition. If you are using a paid version of the software or if you purchased PLUS you can get phone support when customer support is there. Otherwise, post your question here and someone will try to help.
