Thanks for reaching out to us in the Community, @sharicn.
 

I appreciate the steps you've done and for providing the complete details of your concern. I'm here to help make sure that you'll get the report that you need in QuickBooks Desktop (QBDT) 2019.

I tried this on my test account for both version of QBDT, but I'm getting the same results for the Budget v.s Actual report. To ensure that I'm on the same page, could you please provide me with a screenshot of the reports on both versions? This will help me deliver the best information for you.

Just in case, you can check out this article for future reference: Create a budget or forecast in QuickBooks Desktop.

I'll be on the lookout for your response and look forward to providing further assistance. Have a good one!
