QFX Won't Import Into Correct Account

Importing a .qfx file has worked for all of my accounts, but one credit card. When I go-->import-->choose file name--> I receive a dialogue that says "1 Account Found" and gives it an "Account Name" "Line of Credit" that is not an account I use, and offers me to choose a "Type" and give it a "Quicken Account Name". If I do so it creates a new account. I need it to import into an existing account, but cn find no way to do that. Any help?
