How do I report estimated taxes for 2 different businesses inside Home and Business?

Since the payments were ultimately paid toward your personal income taxes, you can add the amounts together and enter a total quarterly payment, or you can enter them separately.  Either way, the total estimated payments made will be added together and included on your Form 1040.  The screen where you enter estimated payments will allow you to enter four quarterly payments, or include additional payments as well so that you can enter each one on its own if you wish.

Use the following steps to get started:  

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “estimated tax payments” and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to estimated tax payments”
• Click on the blue “Jump to estimated tax payments” link

I made you a screen shot.  You can enter them all individually if you want or if they are on different dates.

Thanks for the great insights and replies!

To be sure the IRS can match amounts paid exactly, I input each additional payment amount and date.

All done and return efiled!

Thanks! This is exactly what I did.
