As an F-1 Visa holder who has not been in the United States for at least 5 years, you are exempt from the substantial presence test and you will be considered a Nonresident Alien. TurboTax does not support Form 1040NR but you can go to the following website https://www.sprintax.com/ which is specifically designed to help in preparing your nonresident alien tax return.
If you have been in the US for less than 5 calendar years, you would be exempt from paying FICA tax (Social Security and Medicare). However, you would still need to file a nonresident federal and state returns if you earned income in 2019.
