Deductions & credits

So correct me if I am getting the idea you are trying to convey: The 91000 that was given out to reimburse payments for taxes is to be distributed as gifts to each person.  I would have to file a gift tax form.  How would I report this in the final return of dad's estate so that it will not show as undistributed net proceeds which could be taxable in following year?  I also had a loss of over 11000 because of the difference between the basis and the sales price.  Turbo tax in review said that I could claim the loss by carrying it back for a refund but i'd have to file a certain form.  Can you tell me what that form is?  It disappeared before I recorded the form number and now I can't find it.  I can't think of anything else that hasn't been disclosed--oh, my father had written a letter to each of his siblings heirs stating his intentions, and we have a copy of that with his papers.  I really appreciate your help.
