@MMNOP , first apologies for late reply. To be sure I understand your situation,
(a) You are on a Non-Resident visa ( F-1), your spouse on F-2
(b) you have a child born in the USA ( eligible for citizenship)
(c) you entered USA on F-1 in 2018 and therefore , assuming that you had not been in the USA at anytime during 2016 or earlier, you are exempt from counting days present till 12/31/2022-- absent an adjustment of immigration status.
Give the above , you need to file as a Non-Resident Alien -- form 1040-NR ( which is not supported by TurboTax -- use SprinTax or similar , Tax professional or talk to your school foreign student office ).
Note that form 1040-NR allows ONLY two filing status --1. Single or 2. Married. You are effectively treated as a single ( for personal exemption -- currently being ZERO ) AND you can only use itemized deduction .
If you need more help -- please tell me 1. which country are you from; 2. Is your spouse form the same country and if not then which country; 3. Is this your first student or other entry into the USA; 4. Is your spouse and your child living with you in the USA; 5. are you on scholarship or family help from your home country OR are you on a scholarship/stipend from your school ; 6.Is your income from working on campus or what?
