State tax filing

Thank you all for answering but I'm confused as ever now.  I feel as if I'm getting mixed answers and my question isn't being directly answered so a lay person like me can understand.    I just need to know:  do I use the same figure in COST OF OTHER BASIS  and SALE PROCEEDS?   Since the FMV  and the amount the house sold for, are the same?  I have learned the sale proceeds are gross and not the check I received after all commissions, taxes etc. are taken out.
