@Vanessa A , oh no, I was used to TT Premier hand holding me throughout the process, I don't think that form popped up when I added my estimated payments. I've already submitted my tax return, is that something I can send in separately? If I don't send it at all, will IRS eventually refund me? The penalty amount isn't too big of a deal, so I can wait, but it's good to know where I messed up.
Edit - I double checked and I see Form 2210 for my state. It seems like I was correct, TT did the estimated voucher payments on "Total Payment (after deductions/credits)" and not "Total Taxes", that's where the discrepancy is.
