to avoid understimated tax penalty the total of your timely estimated tax payments and withholding (IRS assumes 25% of total for each period) must meet one of these criteria.
1) 90% of 2022 tax or
2) 100% of 2021 tax. its 110% if your 2021 adjusted gross income was $150K or more
doesn't the notice show the calculation? you'll have to compare it to the Turbotax 2210 to see where the difference lies.
