If TurboTax did not print out form 1040-ES, you can print them from the IRS website: IRS
Form 1040-ES. There are 12 pages. Scroll all the way down for the forms. It has all four quarters.
- TurboTax does not provide envelopes. On page 5 of the above IRS link, find the address based on the state you live in.
If you want TurboTax to create form 1040-ES forms, see How do I print estimated tax vouchers for my 2019 taxes?
You can also pay directly on the IRS website. You can use a credit card (there's a fee) or have them withdraw it from your checking or savings account (free). See IRS
Payments.
