F-1 to H1-B in a single tax year

Hello -

I am trying to submit my tax return for 2021.

I entered the US in August 2017 on F-1 and my visa status changed to H1-B on 10/1/2021. I looked up the 4011 IRS document and it looks like I qualify as a non-resident alien but I am unable to claim standard deduction on my tax return.

Sprintax is not allowing me to claim Standard Deduction but I have some colleagues that have been able to via Sprintax who have gone through the same process and situation.

I have reached out to the live agents and they have told me that I am ineligible for that but my resident country is India.

Is there someone that can help me with this issue?
