You asked: "Can I file tax if I'm not U.S. citizen? Can I talk to an agent please."
The Free Edition does not have phone support. But your question can probably be answered in this user community forum.
Whether or not you can use TurboTax to file a return will depend on how you are classified for tax purposes. TurboTax can only prepare returns for US citizens and "resident aliens for tax purposes." It cannot prepare returns for non-resident aliens since it cannot prepare Form 1040NR/NR-EZ.
What is your situation? Were you in the USA and had income here in 2019? If so, when did you first come to the USA, and how long have you been here? What visa were/are you under? From what country?
Once you provide more info, I can ask someone familiar with international filing to assist you.
If it turns out that you cannot use TurboTax, we can tell you about an affiliate partner Sprintax (one "T") that specializes in preparing Form 1040NR returns for international filers.
