Get your taxes done using TurboTax

You don't do quarterly filing.  What you do is pay quarterly estimated taxes to cover the tax you will owe on your personal tax return.  1040ES estimated tax payments are like withholding you have out of your paychecks at work.

The first year you don't need to pay estimates as long as you pay in (by withholding) as much as your tax was last year.  But if you will have a big income you should send in estimates so you don't owe too much next April on your tax return.

You must make quarterly estimated tax payments for the current tax year if both of the following apply:
- 1. You expect to owe at least $1,000 in tax for the current tax year, after subtracting your withholding and credits.
 
- 2. You expect your withholding and credits to be less than the smaller of:
    90% of the tax to be shown on your current year’s tax return, or
  100% of the tax shown on your prior year’s tax return. (Your prior year tax return must cover all 12 months.)

To prepare estimates for next year you start with your current return, but be careful not to change anything in your real return or you will overwrite your return.

You can just type W4 in the search box at the top of your return , click on Find. Then Click on Jump To and it will take you to the estimated tax payments section. Say no to changing your W-4 and the next screen will start the estimated taxes section.
