If you were a nonresident alien for tax years 2017 and 2018 you need to file a Form 1040NR. TurboTax does not support Form 1040NR.
See this TurobTax support FAQ for information - https://ttlc.intuit.com/community/forms/help/does-turbotax-handle-form-1040nr-for-nonresident-aliens...
TurboTax cannot prepare returns for non-resident aliens, since it cannot prepare Form 1040NR/NR-EZ. TurboTax has an affiliate partner Sprintax (one "t) that specializes in non-resident returns for international filers (see the FAQ that DoninGA provided in his comment above).
I can ask someone familiar with international filing to further advise. Please answer the following:
- So you are not a USA citizen, correct?
- What country are you from?
- When did you first come to the USA, and how long have you been here?
- What kind of visa were you under those years 2017 and 2018 and subsequent years?
- Are you married?
@ pk Are you able to please continue helping the user in this thread when you are next in the forum? Thanks!
