jumbled reports

You can run the verify rebuild tool to detect data damage to your company file and fix it. Note that this process may or may not work for unsupported versions of QBDT.

Let me walk you through how:

1. Select File, then select Utilities.
2. Press on Verify Data.
3. Hit on OK to close all windows. If you see “Your data has failed the integrity check” you need to rebuild your file. If there are no problems with your data, you’re done.

After that, proceed with verifying the data:

1. Select File, then select Utilities.
2. Press on Rebuild Data, then select OK to close all windows.
3. QuickBooks will ask you to make a backup before rebuilding your company file, select OK. If you don’t want to do a backup, select Cancel to continue rebuilding your company file.
4. Once the rebuild's finished, select OK.

For more details about the process, please check this article: Verify and rebuild data QuickBooks Desktop.

Regarding getting a newer version of QuickBooks, you can move and restore your file. 

If you need help customizing your reports, I have attached an article you can use as a guide for the detailed steps: Customize reports in QuickBooks Desktop.

Run the Verify/Rebuild Data utility as mentioned by GlinetteC. You can utilize the trial license for QBD 2021 and compare the reports. You can still purchase the one time license for QBD 2021 or get the subscription license for QBD 2022. 

I haven't heard of QuickBooks doing this sort of thing before. Generally QB reports are quite reliable.

If running on a cash basis, note that the reports are very sensitive to the way your AR and AP transactions are 'linked' to each other. If those links are missing or corrupt, that will cause the reports to change.

Questions:

What do you mean when you write that you can see expenses in your 'statements' but not in 'reports'?  What statements are you referring to?

Is your P&L on a cash or accrual basis?  If cash, are you sure the expenses that are missing are paid with payments dated within the period of the report?
