Do you have foreign income to take the credit against? It can't be used against US-source income.
If you do have foreign income, it sounds like TurboTax doesn't yet know that. Navigate to the foreign tax credit section in Deductions & Credits, then Foreign Taxes to identify the income on your return against which the credit should be applied.
Foreign "general category" income would typically be wages or other compensation and not passive income like dividends or interest. If you don't have any of that type of income to report in 2023, then the credit moves forward until you do (or it expires).
