In
Quickbooks, I do have the option to delete an account. If I go to the
Chart of Accounts and right click on an account, I get a list of options
that include “Delete Account” and “Make Account Inactive”. If I can
delete the account, should I?"
It won't let you Delete. You have Transactions here. If you select that option, you can see this happening. Never make an account inactive if you left a balance and did not Reconcile to end this account at 0.
"Also, I still need to track the type of business expense and if I change it to Shareholder Loan then I won’t be able to that."
Make it easy; don't change a Bazillion things. Just rename and Repurpose this account.
