so the cost or other basis on line e of 8949 of form is what you paid for the home plus improvements you added to the home since you purchase it?

so the cost or other basis on line e of 8949 of form is what you paid for the home plus improvements you added to the home since you purchase it? 

So if I purchase home in 2010 and sold in 2023, does that mean any improvements I made to the home will be added to the basis or column e of part 2 of 8949. Since this was my second home and NOT investment property I will add the "entire" cost of the improve to my "basis"? 

So if I added improvement in 2011 or 2020, this improvement will be added to my "basis" in full?
