@cdwestlund you can amend your 2023 tax return and complete form 2210 and form 2210ai. Be sure to check option C. it's not going to eliminate the penalty (because you didn't may a payment in Jan 2024), but it will permit you to indicate your 2023 income as "lumpy" and you didn't owe estimated taxes in Apr, June and Sept 2023.
the forms are a 'pain' - because in effect you are filling out your tax return by quarter and determining how much income was generated in that specific quarter.
how much was the penalty? it may not be worth the time or effort to amend.
