Hello, @e.ramirez.
I'd be glad to help share information about migrating from QuickBooks Desktop (QBDT) to QuickBooks Online (QBO).
For me to verify this further, are you trying to migrate your QBDT UK data to QBO US? If so, there isn't an option to migrate it that way. Since your QBDT subscription is UK then when migrating it to QBO, the version would also be in UK.
If you wish to use the US version, then, you may need to sign up a new account for QBO US. In this case, your QBDT UK data won't be migrated since the location is different. You have to input the information manually.
For additional reference about data file conversion, you may check this: Moving form QBDT to QBO PDF.
In case you have any other QuickBooks or migration questions and if you're referring to something else, just feel free to add a comment below. I'll be always here to help you!
