You inherited the 3M stock and cost basis of the 3M stock is explained as follows.  Per IRS Publication 551 (page 15), the basis of property inherited from a decedent is generally one of the following.

 

  1. The fair market value of the property at the date of the individual's death.
  2. The fair market value on the alternate valuation date if the personal representative for the estate chooses to use alternate valuation. 
  3. The value under the special-use valuation method for real property used in farming or a closely held business if chosen for estate tax purposes. 
  4. The decedent's adjusted basis in land to the extent of the value excluded from the decedent's taxable estate as a qualified conservation easement.

Since the Solventum stock was spun-off and not inherited, Something else or I purchased it may be the best choices for the question How did you receive this investment?

 

If you paid $100 for four shares of 3M, your cost basis in 3M is $100.

 

After the spin-off, you have four shares of 3M and one share of Solventum and your cost basis is still $100.  The cost allocation would be four shares of 3M $80 and the one share of Solventum would be $20.  

 

  1. At the screen Look for your sales on your 1099-B, select Continue.
  2. Enter the information.  Select The cost basis is incorrect or missing on my 1099-B.  Continue.
  3. At the screen We noticed there's an issue with your cost basis, select I know my cost basis and need to make an adjustment.  Continue.
