" ... based on the income I receive each quarter."
Form 2210 requires evenly spread estimated tax installments.
That's why you have a penalty.
What is your 2022 tax ?
If your estimated tax + withholding is each period 25 % of that amount ( x 1.10 if your AGI is over 150,000)
you will avoid an underpayment of estimated tax penalty in 2023.
This is the prior year's tax rule for estimated tax.
April 18th is the due date for the first 2023 Estimated Tax installment.
