Hi Jamie,
Please try below options.
There may be results already available in PCL4 cluster.
1. Go to Tools --> Overwrite results --> Online/Background in Tax Reporter and see if you can see the forms.
2. Go to Utilities --> Delete Prod PCL4 in Tax Reporter, Once done, rerun Tax Reporter and see if forms are generated.
If it does not work may be you will have write back to SAP to investigate.
There are changes to Tax reporter with notes 2199274, 2214237 and 2220405 in HRSP 92 that may have caused issue.
Thanks,
Ameet
