I appreciate you for coming back to this thread, EKFPROMO.  I'll shed some light about about how reports are moved from QuickBooks Desktop (QBDT) to QuickBooks Online (QBO).

Once the migration is finished and you are reviewing the reports in your QBO account, you may notice differences compared to the data shown in QBDT. For instance, accrual basis reports in QBO will match those in QBDT, while cash basis reports may not. Additionally, the two programs do not have the same reports.

In terms of taxes, sales tax will not be copied for all transactions; some will be transferred as journal entries. For more information, feel free to refer to this article: Learn how features and data move from QuickBooks Desktop to QuickBooks Online. 

I've also added this helpful resource that you can open for guidance in setting up your QBO account to start working: What to do after you move from QuickBooks Desktop for Windows or Mac to QuickBooks Online. 

Moreover, did you know you can schedule a free consultation with our QuickBooks Live Expert Assisted? They can offer tips and guidance about managing your QuickBooks Online account, specifically for reports.

Keep me posted if you have any other concerns about managing your QBO account. Just visit this forum anytime and I'm just around the corner to help.
