I completed my tax returns on 04/24/21. I got a message saying I had a penalty due to excess Roth IRA contribution. This is inaccurate and needs to be corrected. How?

A message from whom exactly?  Did you incorrectly record it in the program as Contribution, rather than a Conversion?

I didn't overcontribute, the confusion is due to a CONVERSION from a different retirement account.  I did not exceed the limit.  I spoke to my financial advisor about this.  The taxes have already been filed and I've received my refunds, but I do not want the penalty obviously.  How can I correct this?

It would only be a contribution if you entered something in to the IRA Contribution interview.    If you did then remove it on an amended return.

A conversion is only entered in the 1099-R section and you say that you "moved" the money to another retirement account and converted it to a Roth.   That would put the taxable conversion amount on the 1040 line 4b unless you had a non-deductible basis in the IRA, then the taxable amount is calculated on a 8606 form.
