"I need the cost basis on 32 shares of MetLife stock"
Look up the closing price of MetLife on your mother's date of death and multiply that by the 32 shares. That's your basis in the 32 shares of MetLife.
Then multiply the total MetLife basis by 10.3635%. That's the basis allocated to the 2.909091 shares of Brighthouse you received. (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwismpCb8PnYAhXqq1QKHYx1DI4...)
Then multiply that total basis of Brighthouse by (.909091/2.909091) - .3125 - and that's the basis in the fractional shares you sold
Using the "Stocks, Mutual Funds, Bonds, Other" interview enter the sales date, the description of what was sold, the $53.37 as the proceeds, and whatever the above math dictates as the basis. In the date acquired field enter "inherited." That will make the gain or loss "long term", which it is according to tax law.
