Dual Status return

Hi!

I moved from F-1 OPT to H-1B in March, 2019. I started on F-1 in August, 2014. My understanding is that I am a non-resident alien between January and March, 2019 and resident alien after that. If I file dual status return, I cannot claim standard deductions, but FICA taxes will not be applied to January-March period. Having read several other posts on this website, it looks like I could file as a resident alien for the entire period. If I do this, would I be able to claim the standard deductions? And, where in the process do FICA taxes enter - I do not see this field applied anywhere in the Turbotax software as far as I can tell. How would I pay this?

Thank you!
