I had previously filed my 2019 return and have received my refund, but it included a penalty for underpayment. Subsequently I've found a small dividend that I'd received and reported to the IRS which I missed when filing the original return. So I'm in the process of filing an amended return to acknowledge/report this. I had also gathered-up all my income/expenses per quarter and completed form 2210, which now states that I'm not subject to a late payment penalty. The net of what I still owe for the missed dividend coupled with a refund for the previously paid payment penalty would be in my favor and I should receive an additional refund. However, even though the form 2210 in the amended return shows no penalty, I still owe a small payment related to the missed dividend. It's as though it didn't take into consideration the penalty payment in the original return. How should I handle this?
