@Garridolecca , having read through your interactions with @mesquitebean , since you have two different posts, let me summarize what I understand as the situation ( please correct in this thread as required )
1. You are from Peru
2. You entered USA in 2017 with F-1
3. You started OPT in 2018
4. Your status was adjusted to H-1B in October of 2019
And assuming that this was your first F-1, you would have been under the exempt category till 12/31/2021. However because of status adjustment your days present in the USA ( towards Substantial Presence Test ) starts from the date of adjustment. Therefore:
(a) you are a Non-Resident Alien for the year 2019 -- you have to file a return using form 1040-NR or 1040-NR-EZ . These are not supported by TurboTax and you would have to use SprinTax, or similar or Tax Professional familiar with international filing --- or seek help from your school , if you are still associated with them.
(b) you do have the option of requesting to be treated as a resident for the year 2019 ( and thus be able to use TurboTax )--- this will also expose your world income to US taxes.
If you need help on how to apply for the First Year choice, let me know and I will come back and help
