How do I adjust a balance in a loan account?

Rod F.

I've been tracking a loan on an automobile repair job. I've got the wrong balance. I tried entering an adjustment to it, but I chose the loan as the Category, but Quicken informed me that I'd be paying into the account from the account (I think that's what it said, at least that's what I understand).

So, how to I properly adjust the loan balance? What should I use for the category?
