Thank you so much! You have been EXTREMELY helpful. I will reach out to DFAS.
(For clarification, I'm the one that set up the HSA and I did know DFAS was contributing to it. I inputted my HSA's 1099-SA when filing my 2019 taxes but the 5498-SA had not yet been issued to me at that time so I didn't know anything about it. I came across the 2019 5498-SA when I was on the HSA website looking for 2020's 1099-SA. That's why I'm questioning it now.)
Thank you for your help!
