You have to file a dual-status return as were nonresident for part of 2021 and you were a nonresident for 2019 and 2020 as were in F1 visa.
If you have two residency statuses in one tax year (resident alien and nonresident alien), you’re a dual-status alien.
Dual-status aliens must file a combined tax return including a Form 1040 (resident income tax return) and a Form 1040NR (nonresident alien income tax return).
You were a nonresident alien who changed to a resident alien and is a U.S. resident on the last day of the tax year, Form 1040 is your main return.
Include Form 1040-NR as an “informational statement” and be sure to write Dual-Status Return across the top of it.
TurboTax doesn't support IRS Form 1040-NR. However, TurboTax has partnered with Sprintax to offer 1040-NR tax preparation.
