F1 to h1B Tax situation question

Hi,

Here is my situation. I moved from F1 to H1b in 2021. From Jan to Sep 2021 I was in F1-Stem opt and from Oct to Dec 2021 I was in H1b. My past yearly presence in US is as follows:

Number of days Present in 2021: 365 f1 and h1b

Number of days Present in 2020: 366 f1

Number of days Present in 2019: 347 f1

Number of days Exempt in 2021: 273. (365-92) . 92 being the number days in h1b

 

1. I read somewhere in some post that TurboTax doesn't cover for F1 situation. Is this true? I have my info and everything ready to file stage online. Software says all fine. It didn't take in any inputs to account for resident/Non resident status?

 

2. Not sure if I fall under dual status? Am I a resident or a Non resident?. Does TurboTax cover this?

 

3. The online software applied 3rd stimulus credit. Not sure if its applicable to me?
