Hi Karen, you can copy all of the sheets to your current sheet, but… I would suggest that you use this sheet separately from your primary budget sheet at least until you get the hang of it. I woudl hate for you to mess up your current budget and you learn the ropes. Tiller allows you to connect up to 5 sheet to the the Tiller feed so your current and new UE sheet can both be used for now. Then… once you get a hang of it you can transfer it completely to your current budget or just start using the UE sheet as your primary. The sheet yo downloaded has sample data on the Category, Transactions, and Balance history sheets ( these are all Tiller sheets). Feel free to delete all of the data. In addition, there is sample data on the Funding Transactions Sheet that you will want to delete.
While I do have some instructions on the UE sheet, it is for a previous version. Most things still apply, it just has a different look and feel. Take a look at the instruction on this Notion sheet.
Also feel free to reach out to me via the email I sent when you downloaded it.
