Sold my out of state rental property

I sold an out of state rental property in 2019, and I am totally confused on how to fill out TurboTax. I'm supposed to split the property between the house and land? Allocating sales expenses? I know I'm doing something wrong, because all of a sudden I jumped from a refund of about $4k to owing $14k. Are there detailed instructions anywhere on what to do? And yes, the title company held back money from settlement to make sure I filed taxes with the state where the property is, so I have to fill out that state's tax form, too.
