Newly retired

Unless you plan to have income from self-employment or sales from investments after you retire, usually there is no need to have estimated tax payments.

Income from a company pension, tax deferred retirement account such as a 401(k) or IRA can have federal income taxes withheld when the funds are distributed.  You can use IRS Form W-4P for those types of retirement funds and give the W-4P to those plan administrators - https://www.irs.gov/forms-pubs/about-form-w-4-p

If you will also be receiving Social Security payments you can request to have federal income taxes withheld from those payments.  

Go to this Social Security Administration website for information - https://www.ssa.gov/manage-benefits/request-withhold-taxes

You can use the TurboTax calculator TaxCaster to get an estimate of the taxes owed for the income you expect to receive - https://turbotax.intuit.com/tax-tools/calculators/taxcaster/

You can also use the TurboTax program for calculating the estimated tax payments and print the Form 1040-ES.

See this TurboTax support FAQ for information - https://ttlc.intuit.com/turbotax-support/en-us/help-article/estimated-taxes/turbotax-calculate-next-year-federal-estimated/L9a7GqBR4_US_en_US

Estimated tax payments cannot be made through TurboTax.  You would have to use IRS Form 1040-ES and mail the form to the IRS with a check for the payment.  The Form 1040-ES has worksheets you can use to calculate the estimated taxes - https://www.irs.gov/forms-pubs/about-form-1040-es

Or you can use the IRS payment website to pay estimated taxes - https://www.irs.gov/payments

In TurboTax you would have to enter the estimated tax payments that you made during the tax year.
