@Kayla37 - I am guessing that the Schedule K-1 has a value in box 2 (rental income) and then in box 20 you have a code Z. Tell TurboTax you have a code Z and don't put an amount (because often there are multiple codes in box 20).
On subsequent screens, TurboTax will ask you about Code Z: Section 199A information. Expand the top line about business income (loss) and then you will see the line for rental income (loss). The second line from the bottom (in 2023) lists "UBIA of qualified property" which is often listed on Schedule K-1s as Unadjusted Basis of Assets.
UBIA stands for Unadjusted Basis Immediately after Acquisition. If you put it all together it would be the Unadjusted Basis [of Assets] [Immediately after Acquisition].
