Don't change anything on your return. Try linking your TurboTax and Credit Karma accounts.
Credit Karma and TurboTax are separate products, and each requires a separate account. You can’t use your TurboTax login information to sign in to Credit Karma, and vice versa.
If you have existing accounts with both TurboTax and Credit Karma, see the Credit Karma Help article Linking your TurboTax account to Credit Karma for guidance in linking your accounts.
