The source of the excess contribution error, in my case, was that I did not indicate that my healthcare plan is a high cost deductible plan. I searched my employer's extensive benefits website and nothing indicated that it is or it isn't a high deductible plan. That said, I do have a high deductible to cover my family and me.
So, once I confirmed that my employer and I did not contribute over the permissible $8300 for 2022, I was able to determine the source of the error, i.e., if you don't indicate that you've a high deductible healthcare plan, and you contribute to an HSA, then the application identifies this as excess contribution.
Again, this worked for me. It might not apply to everyone.
