Dual status tax returns (F-1 H1B)

I was on an F-1 visa from August 2013 till September 2017 and on an H1B visa from October till now. I am single. I filed extension for the 2017 year and now as I am Resident for tax purpose as I satisfy Substantial presence test, I will elect for the first-year choice and file Dual status tax returns. I have created a statement for the first-year choice. I am going to take a standard deduction and US-India tax treaty itemized deduction for the non-resident part and none for the resident part. I will be attaching 1040 first then 1040NR both with “Dual-status return”.

I am confused about how to compute taxes and complete federal forms now

1. Do I have to individually complete 1040 and 1040NR with respective income, use individual tax brackets to calculate tax for each? No need to put total anywhere?
