How do I start my estimated return for 2023 now? I run my own business and want to calculate my estimated tax

The TurboTax desktop editions for tax year 2023 will not be available until mid-November.  The online editions should be available in early December.

You can use the IRS Form 1040-ES worksheets to determine any estimated taxes for tax year 2023.

Go to this IRS website for the Form 1040-ES - https://www.irs.gov/forms-pubs/about-form-1040-es

Estimated tax payments for tax year 2023 can be paid using the Form 1040-ES and mailed to the IRS or on the IRS payment website here - https://www.irs.gov/payments

You can try TaxCaster (currently for the 2022 tax year but should give you a reasonable idea).
