How do I pay underpayment to Social Security from my 1099-misc?

In TurboTax Online, Federal withholding tax not already entered on a W-2 or 1099 may be entered as follows:

 

• Down the left side of the screen, click Federal.
• Down the left side of the screen, click Deductions & Credits.
• Click the down arrow to the right of Estimates and Other Taxes Paid.
• Click to the right of Income Taxes Paid.
• Click the down arrow to the right of Other Income Taxes Paid.
• Click to the right of Withholding not already entered on a W-2 or 1099.
• Click Yes.

If the income reported on the IRS form 1099-Misc is self-employment income reported on Schedule C Profit or Loss From Business, a self-employment tax would be computed for the income on IRS form SE.

 

Is this what you are referring to?  Or something else?

 

To report the income as self-employment income in TurboTax Premium Online, follow these steps:

 

• Down the left side of the screen, click Federal.
• Down the left side of the screen, click Wages & Income.
• Click on the drop down arrow to the right of Self-employment.
• Click to the right of Self-employment income and expenses.
• At the screen Your 2024 self-employed work summary, click Edit.
• At the screen Here's your info, select Add income for this work.
• Select Form 1099-MISC.

 

 

Hi JamesG1.  TY for the detailed reply.  Very helpful to know about the form SE.  Would your instructions apply to the downloaded version, not online, of TT Premium?  Looks like this year I'll need to pay estimated taxes in order to avoid a penalty.  Can I use my TT to pay estimated taxes in order to avoid any penalty?  Thanks very much.

The instructions are similar for TurboTax Online or one of the desktop versions of the program.  The main difference being that when using the Online version, the navigation steps are centered on starting with the menu on the left side of the screen and often you need to click a down arrow to expand a category.  Using a desktop version, the navigation begins at the top of the screen and all the categories are fully expanded already.  The highlighted terms in the guidance are generally the same for either version.

 

You would not use TurboTax to pay estimated taxes for 2025, but you can use the program to generate your vouchers so that you can pay by check or online directly to the IRS.  See the following TurboTax help article to get started with creating your estimated payment vouchers:
