In January 2020, I made a $3500 contribution to my HSA account with the intention of deducting it for tax year 2019. I filed my 2019 taxes with the $3500 deduction included. Later in the year, I noticed in my HSA account that the $3500 contribution was marked as being for year 2020. I contacted the HSA administrator to have the year corrected to 2019, however they told me they could not change it because the filing date (in this case, July 15, 2020) had already passed. I'm not sure what I should do about this situation. I assume the HSA account administrator will send this contribution to the IRS as being for 2020, yet I filed my return for the same contribution to be for 2019. Do I need to Amend my 2019 tax return to prevent an audit situation? Is there any other way to have this contribution changed (from IRS standpoint) to 2019? Thank you!
