We need assistance with Marks to open fiscal year 10/1/2022-9/30/2023. Can you help?

Question

I am the new controller of the Savannah Jewish Educational alliance/Savannah Jewish Federation. We need to close fiscal year 10/1/2020-9/30/2021 and open fiscal year 10/1/2022-9/30/2023. I am told that someone needs to remote into my computer. This issue is rather urgent
