Have you "reported" (added to your LAR) the first LOC this year? If so then you can delete it and just report the second one. Or, if you want to keep that one on the LAR then you can and report the increase under the new loan number.
If you haven't added the first one to this year's LAR, then you can report the whole amount of the second one.
Life is not the way it's supposed to be. It's the way it is. The way you cope with it is what makes the difference.
