My SOL taking into account my tax return is now available online and a refund should issue during the week. Correct 2020 USC bands were applied, so the issue with these being out of date is specific to the offline form.
It seems my initial post was a little misleading. The document I received on the 1st was actually an Employment Detail Summary, even though I accessed it through the SOL area on Revenue.ie.
