2019 Tax filing - my Visa status changed from F1 to H1B and wife's Visa status changed from F2 to H4 and Son holds US Citizen

Hello Team,

 

I came to the US on 2014-12-25. I was on F1 until 2019-09-30 and then my visa status converted to H1 on 2019-10-01. And, currently, I am in the US.

My wife entered the US on 2017-02-22 on F2 and her F2 converted to H4 on 2019-10-01.

My son holds US Citizenship.

 

I filed all my previous years' returns as a Non-Resident Alien (1040NR).

 

On what category should I file the taxes? Non-Resident Alien or Resident Alien?

FYI: I stayed more than 300 days in each previous year (2015, 2016, 2017, 2018, 2019 years).

 

Also, Am I eligible to claim COVID-19 benefits offered by the US Govt (at least for my son)?

Thanks in advance.
