If you owed taxes on your 2019 tax return, TurboTax will print estimated tax payment forms for you to use to keep from owing on your next year's return. You can just ignore them if you don't think you need to pay estimated taxes.
Filers can sometimes owe underpayment penalties if they don't withhold enough or pay estimated taxes during the year. Generally, most taxpayers will avoid this penalty if they either owe less than $1,000 in tax after subtracting their withholding and estimated tax payments, or if they paid at least 90% of the tax for the current year or 100% of the tax shown on the return for the prior year, whichever is smaller.
