So you have already filed your 2017 return?
CAUTION:
I can tell you how to open up your already-filed 2017 return to go through the W4 and
estimated taxes interview. It's OK to use that section, but do not go
back into other areas of your return to change things or experiment,
since any changes would be saved and mess up your return.
**********************************
You can go through the section "W-4 and Estimated Taxes" to
figure your customized 1040-ES quarterly tax payments. There is also a place in
that interview to enter what you have already paid for 2018 (if
applicable), and it will let you include any expected income changes or
any other changes you have for 2018.
- Log in and go to "Your Tax Returns & Documents". Click on that line or the word SHOW to expand, then choose 2017.
- Since you have already filed, you'll need to open your return back up.
- Choose "Add a State." (you don't really add one; that's just to get the return to open back up.)
- Once the return is open and past the blue-green screen, click in the left menu column on Federal.
- Then at the top choose subtab "Other Tax Situations"
- Scroll way down to last category "Other Tax Forms"
- Find topic "Form W-4 and Estimated Taxes" and click Start or Update.
- If you need to adjust withholding, go through the W-4 interview.
- If you don't need the W-4 (withholding) interview, you can skip that part and go to the 2018 estimated taxes interview.
- You may get a screen that says "Review your Estimates for 2018?" and asks "Do you want to adjust/review your income or deductions". Say YES (or Review Now), so you can get to the additional questions.
- You will go through a lot of screens asking about expected income and deductions.
- Finally, you will come to a screen that says "Enter Payments You Expect to Make."
- There are some boxes there that say "Enter estimated tax payments you've already made for 2018."
- Next screen will ask "which method" to use to calculate your 2018 estimated payments.
- Next screen will ask if you want to print vouchers.
