If I think TurboTax incorrectly calculated my taxes, how can I get TurboTax to correct it and help me receive a refund because of their error?

TurboTax accepted my 1099-MISC self employed income as well as my 1099-NEC as bonus income.  However TurboTax calculated then both as regular earnings.  The TurboTax website says bonuses are taxed at only 22%. This is not what happened on my tax forms.  TurboTax simply added the MISC and NEC forms to account for my total self employed income, when they should have been taxed differently.

Income reported on a Form 1099-MISC or a 1099-NEC is entered as Self-Employment income.  The net of your SE incurres SE taxes at 15.3% of net income.

If your net SE income is greater than the Standard Deduction for your filing status you will have taxable income subject to federal income taxes.

Where did you see that you would only be taxed at 22% for bonus income?  Please provide a link.

Employers are required to withhold federal taxes on bonuses at a rate of at least 22% ... maybe that is what you are referring to but the bonuses should be included on the W-2  and not be on a 1099. 

By chance did you get a SPIFF from a manufacturer as a bonus ?   If so those are put on a 1099 ... is that what you got ?
