How do I downgrade back to quickbooks self-employed

You can't do that. Another option is converting your data from QBO to QB Desktop file format and use the trial version to access your historical data for good. Then you will start from scratch in a new account.

We're unable to do that, @smc184.

I'll share information about downgrading back QuickBooks Self-Employed (QBSE).

Please know that we no longer offer QBSE. Thus, the product will be discontinued soon. That said, we can't downgrade back to QBSE. 

However, you can consider checking out the latest QuickBooks Solopreneur. It's a similar product with more advanced features and helps you organize your business and personal transactions, track mileage, and measure your business performance.

For reference, you can check out this article: Introduction to QuickBooks Solopreneur.

Drop by this thread again if you have future concerns with QuickBooks Solopreneur or with managing your accounts and subscriptions. I'm always ready to offer help. Good day ahead.
