I owe don’t know how but I do any way trying to set up the amount and it says I have to subtract line 8 from 7 and it’s zero so what do I do

What form are you trying to complete?

You may want to review your tax return to make sure it is correct, here's how:

While in TurboTax follow these steps:

1. While in your Tax Home,
2. Tax Tools on the left hand side of your screen,
3. Select Tools,
4. Select View Tax Summary,
5. Select Preview my 1040 on the left hand side of your screen.

If you haven't filed your return, you can change anything in TurboTax by going back to the area and the item that you entered and select Edit next to it.

Also, you may want to file a new W-4 with your employer so you don't have to pay additional taxes next year.  Here is the IRS Tax Withholding Estimator that may help you with determining how to fill out your W-4.
