Ahhh, I thought the $448 was the amount you owed....not the actual penalty.
.....not always easy to see the penalty tax calculations when using the Online software, since, if the default calculations are used, the form 2210 may not appear.....while those of us who use the Desktop software can always force the display of the form 2210.
You can go to the Print Center, and download all your forms and worksheets to a PDF file, and see if it's there (you'll have to pay for the software, if you haven't already). And if it's not there, then you'd need to go thru some of the Underpayment Penalty interview steps again on the Other Tax Situations page, and try the withholding when paid steps first...that might force the 2210 without messing with doing a full annualized income.....but you would need to know amounts&when of actual Federal withholding was done for whatever tax forms you do have entered.
(Of course, perhaps try @NCperson 's suggestion too)
