Circumstances required that I get three new account numbers from my credit union. Two savings accounts and one checking account. During set-up of these new accounts in Quicken Premier I've managed to link the Checking account/register to the Savings account number at the CU. Check register goes back to late 2013, so I do not want to delete it. (The other savings account has the correct credit union account number tied to it.) Can you edit an account number? I don't see how. Seems, Quicken did not make that provision. It seems if there are problems, delete the account and try to start over. Like I said above, I do not want to delete an account with historical transactions. Related: How do you edit an account nickname? I've made a back-up file, now residing on a USB Flash Drive.
