How to Report Spouse’s Foreign Self-Employment Income in MFJ

I am a U.S. resident alien filing as Married Filing Jointly (MFJ) with my husband, who is a self-employed sole proprietor in India. He lives in India, his business is based there, and he has no U.S. income or clients. He doesn't even have SSN and I'm applying ITIN for him. I want to correctly report his income in TurboTax and determine if he qualifies for the Foreign Earned Income Exclusion (FEIE) or Foreign Tax Credit (FTC).

1. Should I enter his income under Self-Employment Income & Expenses (Schedule C) or under Foreign Earned Income & Exclusion (Form 2555)?
2. Will he be subject to self-employment tax (15.3%) in the U.S., or does India’s Totalization Agreement provide an exemption?
3. Since he pays income tax in India, would the Foreign Tax Credit (Form 1116) be a better option than the FEIE?
4. If FEIE applies, how do I ensure TurboTax calculates it correctly?

I want to make sure I report his income correctly and minimize double taxation. Any guidance would be greatly appreciated!
