Silly question: Where, exactly, does one enter the BASIS of an investment property in TT?

Many articles around what is and in not included in basis, how to depreciate assets and the like, yet NOTHING I have yet to locate stating where the BASIS field is located?

 

Doubtful this would be the Enter Common Expenses, because that is annual and I am expecting Basis to be a single field only used when purchasing or selling a property.
