You nailed it Macuser_22. I looked back and the same thing happened in 2016/2017. It was due to a distribution code 8 on my 1099-R that I received back then. I'll get the 1099-R next year to settle up. This wasn't due to overpayment on my part, it had to due with company checks based on differed distributions across all employees. Small company with no matching, so most people didn't try to max it out like I did. Thanks for clarifying!
