Form 1099-SB, Seller's Investment in Life Insurance Contract, will be filed by the issuer of a life insurance contract if they receive a statement from an acquirer in a reportable policy sale provided under section 6050Y(a) or they receive notice of a transfer of the life insurance contract to a foreign person. You don't need to enter this form on your return. See here for more information about Form 1099-SB.
Form 1099-LS is issued to the person to whom payments were made to acquire a policy. In general, a reportable policy sale payment recipient (payment recipient) is any person that receives a reportable policy sale payment in a reportable policy sale. There is not a specific place to enter Form 1099-LS; you can enter your cost basis (premiums paid) and the amount you received in the Investments section of TurboTax:
If you received proceeds in excess of your basis (premiums paid), the excess is a capital gain from the sale of an investment.
