Hello, @renayoung.

Since you already updated your QuickBooks Desktop 1999-2000 to QuickBooks Desktop Pro 2016. That's the reason why some features in the system are different.

Also, the transactions are now updated especially the VAT elements due to the migration process. You can check other reports as there may be issues on the allocation of the VAT forms.

I've added our help articles hub that you can browse in navigating your account in QuickBooks.

You're always welcome to come back on this thread if you need anything else. Keep safe and be well.
