Glad you dropped by the QuickBooks Community. I want to make sure this concern with your QuickBooks Self-Employed trial account gets taken care of.
Did you just sign up to the QuickBooks Self-Employed free trial? If so, you should be able to log in and have a full access to its features for 30 days.
Since the system says that your trial is over, I’d recommend reaching out to our QuickBooks Self-Employed support. They’ll be able to check the account and verify what’s causing you to get that prompt.
Please let me know if there’s anything else you need. I’ll be here to help. Have a good one!
