you should also review form 2210 to see why there is a penalty computation. you can meet the 90%/100% rule for the whole year but under the default method 1/4 of that amount must be paid in on or before each of the following dates 4/15/2023, 6/15/2023,9/15/2023, 1/15/2024.
if you had a large amount of income if the later part of the year and paid an estimate to cover the taxes, under the default method there would be penalties for the earlier periods. the only way to avoid this is to use the Annualized Income Installment Method on page 3 of the 2210
