I confirmed with HR people that my HDHP coverage for each month in 2021 and 2022.
"The issue is that for my 2021 tax return I stated I didn't have HDHP. " What is this referring to? On what screen did you state that you did not have an HDHP?
For my 2021 tax return this question came up at the last section when reviewing my tax documents. Specifically the question on the tax return was "What kind of High Deductible Health Plan" did [name] have on December 1, 2021?" and you answering "Self" or "Family".
