So, this is going to sound like a very basic suggestion, but when you go to the Accounts sheet, you need to click on the green arrow in a cell in the Account column and choose the new account to populate that row. The accounts don’t automatically show up. You have to populate a row with an account. (Sorry, if this comes off as super basic. I can assure you I don’t think you or anybody is an idiot. I just got tripped up on this at one point.)
