On 1040/1040SR, it says line 11 is too large. Line 11 is zero. The amount on line 10 is a negative number. Did something go wrong?

Could you manually go through the forms section and delete all of the 109NEC and the section C duplicates using the link provided below:

I think the fact that line 10 is negative indicates that you're not eligible to defer any SE tax (because you've already paid more federal tax than your self-employment tax due and the IRS won't let you defer what you've already paid).

So doing the following solved this problem for me:

1. Return to the Deductions & Credits section of Federal Taxes
2. Click "I'll choose what to work on"
3. Scroll to "Tax relief related to COVID-19" (and click "Show More" if that's shown)
4. Next to "Self-employment tax deferral" click Revisit or Update
5. When asked "Do you want more time to pay your self-employment tax?" answer No.
6. Re-run the Federal Review
7. If it complains that some boxes that say 0 should instead be blank, just delete the 0s

After that Federal Review completed successfully. If that doesn't work for you, perhaps one of the answers to this equivalent question will.

This is a question because of initially qualifying to defer a portion of your self-employment tax, before all the details were entered into the return. Once a refund was established, the deferral was no longer an option.

If you return to the section directly, you may not see the screens necessary to adjust this since you no longer qualify for the option.

The easiest and fastest solution is to enter nothing--leave the response blank.

But, if you are still experiencing unexpected results, then temporarily trigger a balance due by adding income long enough to decline the SE tax deferral option, then remove the extra income.

To do this in TurboTax, follow these steps:

Enter a temporary amount as income in the self-employment section that will result in you not having a refund.

1. From the left menu, select Federal.
2. From the Income & Expenses, scroll to Self-employment income & expenses and Edit/Add.
3. At Your 2020 work summary, select Edit.
4. Under INCOME, select Add income for this work.
5. Add Other self-employed income, includes 1099-K, cash, and checks and Continue.
6. At Type of income, enter Temp income to remove deferral and enter a large amount, such as $100,000 and Continue.

Decline to defer any self-employment tax.

1. From the left menu, click on Federal.
2. Click the second tab from the left, Deductions & Credits.
3. Scroll down to Tax Relief related to Covid-19 and Revisit.
4. Select Self-employment tax deferral and select Revisit.
5. Answer Yes at the next screen to get back to Let's start by getting your eligible income.

1. Enter 280/366ths of your income to reflect the income from March 27-December 31, 2021. 
   1. This amount should be the same as the correct amount on Line 18 of Sch SE.

1. Select Continue.
2. At Tell us how much you'd like to defer, 
   1. Enter 0.

Remove the temporary income.

1. From the left menu, select Federal.
2. From the Income & Expenses, scroll to Self-employment income & expenses and Edit/Add.
3. At Your 2020 work summary, select Edit.
4. Under INCOME, select the Trash can icon next to Temp income to remove deferral and Continue.

For more details, see TurboTax Expert @DawnC's answer here, about 2/3 down the page: Resolve Sch SE-T Max Deferral Line 18 must be entered.

If the error is still in the return, it is because Sch SE-T or Sch SE-S is not updating properly. To update the return automatically, it is best to close out completely and close the browser, as well. Re-open in Chrome on a PC.

1. Delete the Sch SE that applies--(Sch SE-T is for Taxpayer, Sch SE-S for Spouse)--by following these steps:
   1. From the left menu, select Tax Tools.
   2. Select Tools.
   3. Scroll to Delete a Form.
   4. Scroll to Sch SE-T and/or Sch SE-S and select Delete.
2. Return to the self-employment income & expenses interview in the Income & Expenses section and select Edit/Add.
   1. Select Edit for your business.
   2. Scroll down to Done so that the Sch SE is recalculated. 
   3. Finish any other questions in the self-employment interview and click Continue.
3. Review the return again.
