It depends. If you only attended a training and were not there in any type of self employment capacity then you can add the income to your tax return using the steps below. Do not enter the Form 1099-NEC which is used and identified as self employment income.
If this was issued from your employer, then it was incorrectly reported and should have been included with your W-2. You can use the steps in this link to correct it.
If you did enter it you must delete it before you use the steps below.
