We can customize the report, JanKron.
This way, we'll have the option to filter the report to show only the transactions for the year 2020.
You can do that by clicking the Customize Report button on the report. Then, select This Fiscal Year on the Dates field. Click OK and then click the Print button. Select Save as PDF.
I've also added this article for more informaton when customizing report: Customize Report in QBDT.
I'll be around if there's anything that I can help. Take care!
