Form az-140es wants me to put O/P? No idea what it wants me to put in a little box. There's a screen with stuff I don't understand

So if we didn't make over 150,000 I put 0?

It's hard to tell.  I'm unable to generate a screen displaying O/P, as you describe, but to get back to relevant section of TurboTax Online to address the $150,000 income issue: 

1. Select Tax Home in the left pane
2. On the Hi, let's keep working on your taxes! screen, select the dropdown on the right side of the State Taxes box, then select Start, Continue, or Review/Edit
3. If the You've already got a head start on state taxes screen appears, select Let's get started.  Otherwise, in the left pane, select Prepare State
4. Proceed through the screens until you come to the Status of your state returns screen
5. Select Edit to the right of Arizona 
6. Proceed through the state screens until, late in the state interview, you come to the Estimated Taxes for 2024 screen
7. If you didn't make estimated payments in the past, and you don't expect your Arizona income to be at least $150,000 next year, select No

 

If this doesn't correct your issue, post a screen shot of the page you describe in your original post, and provide any other information that you can, including the following:

• Did you make estimated payments in the past?
• Do you expect your Arizona income to be at least $150,000 next year?
