You are correct that the software isn't really set up for this scenario.
To get it to use the correct numbers, pretend this was the first time it was a rental (2023).
The two exceptions to that is:
(1) when it asks you for the Basis, use the lower of (a) ADJUSTED Basis (usually your original purchase price, plus cost of any improvements, MINUS the total depreciation from when it was a rental the first time) or (b) the Fair Market Value when it was converted to a rental in 2023.
(2) When you sell the property. But I won't go into that now because it doesn't apply to your current situation.
