Using Foreign Tax Credit Carryover

Hello experts, last year I had FTC Carryover that I would like to use this year. I am in the TurboTax form listing the FTC Carryovers during the past years (2023-2014). The only year for which I have carryover is 2023. In this form there are two columns: 'Foreign Taxes' and 'Amount Used'. I would like to confirm that, under column 'Amount Used' for the year 2023, I should input $0 as 2023 is the 1st year in which I've had carry over and I've never used it before. Also, I would like to clarify if Turbo Tax will try to use as much of that Carryover in this year's return or whether I need to manually specify the amount to use in 2024. Many thanks!
