Hi jlathanasoulis-g,
Welcome back to the Community. QuickBooks offers the tools and resources you need in order to manage your books with peace of mind. I'll be glad to share more info and help get you back on track with your work.
QuickBooks allows you to enter prior account information. Having the 2021 info on the account is useful for when you need to access/reference that information, however, it's not a requirement to enter that info in QuickBooks. The program gives you the flexibility to pick the option that works well for your business and accounting.
I'll be happy to assist you with navigating the program. Feel free to ask any other questions. I've got your back.
