I sold stock from an employee stock purchase plan. The cost basis included my employer's contribution (which lowered the cost basis). I received a W-2 with the employer's contribution amount. What code do I use on form 8949 column 'f' to adjust the basis so I am not taxed twice on the employer's contribution. Or is the a better way to do. I received as 'supplemental information' what the adjusted cost basis should be.
