Other income

You can preview the information on your 1040 form before you file, when you are signed into your return. In TurboTax Online:

1. Select Tax Tools, on the left, in the black menu bar
2. Select Tools
3. Click on View Tax Summary, first on the list under Other helpful Links.  This will show basic information about the return.
4. In the black menu bar, on the left, click on Preview My 1040
5. This will show a picture of the information on the tax form and there is a vertical scroll bar on the right-hand side, to scroll down the return.  Please look for the amount you see in the Other section and this should tell you which section of the return is generating it.  

After you have paid for TurboTax or registered your copy of the free version,  you may print a copy of the entire return or download it as a pdf onto your computer and review it on a larger screen. It is easier to see details than the preview. This TurboTax Help article has directions. Print return before filing

IF using the Desktop software.......menu item labelled "Other Income Taxes" in the 2021 summary column (Deductions&Credits page) is just the total of Federal+State+Local tax withholding you already entered with your W-2, and various 1099-??? forms.  It can also include State final balance due taxes you paid with your final state tax return last year.

The $$ amount is blue...click on it and it will be broken down for you in a pop-up as to what it includes
