The 2210 form is not shown when I go thru that menu (online version). It only says I need to pay $x for underpayment. This is the first time I have heard of this! I wasn't notified by the IRS. No form is shown is shown in TT, just the message. I looked on my 1040 for 2023 and it says I had an estimated tax penalty (?) of a much smaller figure, after I paid a sizable amount of taxes, shown in line 37. This is all news to me.
