I called IRS and they verified that my ITIN is valid. It's the e-file software that incorrectly sent the email.
"The 96 middle digits is set to expire if it was issued before 2013" or "if issued after 2013 then it'll expire if not used for last 3 years tax return".
Both of those conditions don't apply to me. Issued in 2020 and used to file 2019 taxes.
Thanks for the reply. Appreciate it.
Hope my case helps someone in the same situation.
