I'm a fellow user--not a tax expert--but I can tell you in general how you can try to delete this form from an Online return if you're sure you don't need it.
First a disclaimer:
I know nothing about California returns at all and nothing about that particular CA Form 3554 . So you'll have to decide if deleting it is what you want to do. The steps below may allow you to do so, and may solve your situation if you do not need the Form 3554.. Otherwise, I'll also leave you info below on how to phone TurboTax Support when they open at 5AM Pacific (8AM Eastern).
I assume you have not yet filed your return and know how to get back into the return interview. If TurboTax thinks you are finished, and there is no longer a "take me to my return" button, you can open the interview back up by clicking on "Add a State". That doesn't really add one, but opens the interview back up. NOTE: IF you have already filed the Federal return, do not make any changes on the Federal side.
Does it let you delete the CA Form 3554 there? And does it stay gone, or does it regenerate?
If that didn't get rid of it, here's how to reach Customer Support. TurboTax Support has extended hours on October 15. They are open 5AM-9PM Pacific (8AM-12 Midnight Eastern.)
FAQ: What is the TurboTax phone number?
This worked for me. For some reason form 3554 did not populate the first attempt but the second time the form populated and I was able to delete it and file my taxes. I used my iPhone and logged in TurboTax through my safari browser. Thanks for the help.
On the 3554 question I put in a 0, instead of leaving it blank. This does not apply to me, I went back in and removed the 0 but it still shows up asking for more information. How do I clear this entry?
You are posting in an old cluttered thread from last year. While someone "might" see it here and respond here in this old thread, you'll have greater visibility if you start your own new thread and explain your details there. If you do, then continue to watch both threads.
If you want to start a thread, click the blue "Ask a Question" button at this page:
The question title line has limited space, but there is a box underneath it where you can explain your situation in more detail. In the title line mention Calif. Form 3554 and your issue to attract someone who may be familiar with it.
It's OK to delete forms that you know don't apply to your return, or are duplicated or blank. Here's the general procedure for deleting unwanted forms, schedules, and worksheets in TurboTax Online:
