you may use the 100% of prior year's tax rule (110% if AGI is over $150,000) or
the 90% of this year's tax rule, to avoid penalty.
Form 2210 requires equal quarterly payments. See Line 11.
your W-4 is already spreading withholding evenly
you must make the remaining estimated tax payment quarterly
since you definitely know the prior year's tax if you filed on time,
but not necessarily your current year's tax,
the first rule is the surest route to reach 25% each quarter..
April 18th is the due date for the first 2023 estimated tax installment.
