Form 2210 requires evenly spread Estimated tax + withholding installments.
And you need to pre- pay at .least 90% of your tax
after doing the Turbotax estimate,
make sure each quarter is at least 25% of 90% of your tax.
April 18th is the deadline for the first 2023 estimated tax installment.
if you need to pay and did not, you are already late on the first payment.
