Should I cancel what I paid for a qb self employed subscription yesterday? How do I get my info transferred from qb simple start?

QBSE is a stand alone product. You are unable to migrate data from QBO or QBD.

Good day, paula00grace-gma.

Let me share some insights about migrating data from QuickBooks Self-Employed to Quickbooks Online. 

Currently, the option to automatically convert your QBSE data into other QuickBooks products is unavailable. You'll want to download a .csv file for your transactions and import them to QuickBooks Online Simple Start.

Also, I recommend saving your financial report before canceling your QBSE account. 

To know more about the conversion process, check this article: Switch from QuickBooks Self-Employed to QuickBooks Online.

I've also included this reference for a compilation of articles you can use while working with us: Get started with QuickBooks Online.

Keep me posted if you have additional questions about moving data in QuickBooks. I'll be glad to assist you more.
