Can I use my deceased spouse's Turbo Tax account to help him file tax return for 2024?.

Context:

  • My spouse is American and has been using Turbo Tax to file tax return for a long time. 
  • I am not a U.S. citizen/resident but I got an ITIN number. I don't live in the U. S.
  • We have been filing jointly since we got married.

Questions:

  1. Can I use his Turbo tax account to file the tax return this year? What do I need to pay attention to?
  2. How is the tax refund going to be delivered? I don't live in the U. S. 
  3. Am I correct in that I don't need to file for tax to IRS in the future as I am not a U. S. citizen?

Looking forward to your feedback.
