@ pranjal4 asked: "What do I answer for " Did You support yourself in 2019"? if I am an International student and my tuition and rent is paid by my father."
First, you need to figure out if you can even use TurboTax. TurboTax can only prepare returns for US citizens and "resident aliens for tax purposes." It cannot prepare returns for non-resident aliens. So you need to figure out how you are classified for tax purposes.
"international student'" in which direction? A non-citizen from outside the US studying in the US; or a US citizen studying abroad?
What is your citizenship status? Are you a US citizen, a non-resident alien, or a resident alien. If not a US citizen, then what country? Are you in the US on a visa? If so, what type of visa? And since when have you been in the USA?
If it turns out you can't use TurboTax, we can tell you about an affiliate partner (Sprintax--one "t") that can prepare returns for international filers who are non-resident aliens.
