Hi gocool,
I'm in a similar situation: I entered US on July 5th as a visitor (B2 Visa), had the company applied for a status change that was approved on Aug 2nd and turned me into H1B Status, then I started on their payroll on Sept 1st.
My wife doesn't have SSN or ITIN number and I was struggling with the same aspect with Sprintax. Then I found out that the software OLT supports 1040-NR with First-Year-Choice and you can even use if for free if coming from the IRS freeFile website: https://apps.irs.gov/app/freeFile/results/
Since the beginning I also configured my withholdings as MFJ and got frustrated when noticing how 1040-NR doesn't have that. Did you end up using the First-Year-Choice and filed a 1040?
Base on another comment made here about the 75% aspect I think I misunderstood how First-Year-Choice works because I thought you would have to be in US 75% of the time of whatever timespan you started your life in US, so I'm still confusing. Any hints?
Thank you.
Carvalho
