Had the same question and noticed people have asked something similar since 2019 : how do I delete California Form 3514 because I do not qualify for Earned Income Credit, but I can't submit my taxes online until I fill it out? Here's what worked for me. During the final review, I went ahead and filled in the 3514 questions. Gave it my address, a company name like "TurboTaxPleaseFIXthis" and a business code 99999, and whatever else it asked. Then after the final review found no more errors, I deleted the form. I then submitted my taxes but (and this is key) I skipped reviewing it one more time. If you review the forms again, you will have to reenter the 3514 form, delete it, in an endless cycle. The returns were transmitted without any more issues. To delete a form using the online software, go to the left-hand menu -- this link describes how to delete: https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-forms/view-delete-forms-turbotax-online/L7SZhwCHv_US_en_US?uid=lns0kdqs
