If you have the Desktop program you can do a What-If worksheet.
Go to Forms Mode, click Forms in the upper right or on the left for Mac. Then click Open Forms box in the top of the column on the left. Open the US listing of forms and towards the bottom find the What-if worksheet. It's right under Estimated Taxes.
Or try…Go into Forms View. Once there, at the top of the left column, click on the icon for "Open Form". A popup window will appear. In the text line, type the word "what" without quotes. You should see "what-if worksheet" appear as a selection choice. Double-click it to launch the form.
The Online version does not have the What-If worksheet. You could start another return (don't test in your real return) to test in but it will have 2022 calculations. But one thing you can do is make your birthdate one year less to make you a year older. You don't have to pay for Online unless you want to print it out to see all the forms.
