I mistakenly entered both the contribution for 2022 (that was made in April 2023) and the 2023 contribution (made in Dec 2023). After seeing feedback on my question, I verified that I had included the 2022 contribution on my 2022 Tax Return. Once I removed the 2022 contribution, I no longer get a note/error that I overcontributed to 2023 HSA.
Additional info: I am self-employed and made single contributions (separately) for the full amount for each calendar year.
