I just want to know if I followed all the steps of selling the rental property.

1) I disposed the property in the asset worksheet section- the asset is linked to schedule E.

2) in schedule E worksheet, I put an X in Complete Taxable disposition.

( what's the purpose of putting X) does it prevent schedule E to show up in next yeat tax return.

the 1231 loss is shwing in form 4797

There is a disposition worksheet too?  is the asset worksheet okay to use for disposition.
