Thanks for your reply Lisa and, yes I did that. But is there a specific form/worksheet to list the improvements/renovations? Is it even a requirement? I think not, but just want to be sure. 

You could open a "Preparer Notes" page (F6 PN will get you there) it transmits with the return.  You can create a schedule there if it makes you more comfortable and show your basis computation.

"....step up in basis"

Making improvements to property owned is not "Stepped Up Basis".  That's a completely different tax concept.

Words/phrases are important in this business.

Completely agree, sorry for the poor grammatical hygiene.
