Can I enter estimated Social Security Income for estimating next year's taxes? That is, for 2026.

You can use the estimated tax tool in TurboTax to do that.   Follow the instructions here.

My wife & I both looked and there is nowhere for us to enter strictly Social Security Income for filling out a 1040-ES Estimated Taxes for 2026.

We also went to the IRS web-site and they don't even show a 1040-ES form for 2026.

Please try again,

Are you only getting Social Security this year?   If you only get Social Security you do not need to file a tax return.   Otherwise you need to enter all your income to prepare estimates.

I doubt if that's correct.

Our Joint Social Security Taxable Income for 2026 will be $112,066 and hence our Total Taxable Social Security Income will be 85% of that or $95,256.

Thus, we are looking to for way to estimate the 2026 taxes we will owe.

Ok then enter the 85% under something else like interest.  That will treat it the same way as adding it under Social Security.

You want to make estimated payments so I am sure you have taxable income. Your answer just popped up. Since you are on Social Security, some of your income is predetermined and you need to adjust for the changes.

The estimated payments start with what you expect your adjusted gross income to be for the year. You can use your current return to help you find a starting point. If you decide to sell stock or a second home, you can adjust as you go in making these payments. I suggest the Tax Withholding Estimator.
